A View of the 2008 Presidential Election Results Through the Lens of the Electoral College Spectrum


[Click to Enlarge]

Yesterday, FHQ promised that it would be back today with a look at the impact the reapportionment changes would have had on the 2008 election. More importantly, though, it is instructive to dust off the Electoral College Spectrum and begin to visualize how the seat/electoral college vote shifts will impact the 2012 presidential election. The map above accomplishes the former without much explanation -- Obama would have lost six electoral votes overall in 2008 -- and below you will find the latter.

**The numbers in the parentheses refer to the number of electoral votes a candidate would have if he won all the states ranked prior to that state. If, for example, McCain won all the states up to and including Colorado (all Obama's toss up states plus Colorado), he would have 275 electoral votes. McCain's numbers are only totaled through the states he would have needed in order to get to 270. In those cases, Obama's number is on the left and McCain's is on the right in italics.

***
Colorado is the state where Obama crossed the 270 electoral vote threshold to win the presidential election. That line is referred to as the victory line.
****Nebraska allocates electoral votes based on statewide results and the results within each of its congressional districts. Nebraska's 2nd district voted for Barack Obama in 2008.


Again, this graphic is helpful from the standpoint of ranking the states from most pro-Obama to most pro-GOP, but it also provides a glimpse into what each side has to do in the general election in 2012 to either maintain or win back the White House. President Obama had such a cushion in the 2008 election -- even under the newly reapportioned electoral college -- that the Democrat could lose next year all of the middle column states except the three on top and still win. In other words, the president could yield Florida, Ohio and North Carolina, among others, and still win re-election assuming that the Republican nominee is unable to advance into some of the other seemingly safer Obama states. It is hard not to see New Hampshire and Iowa -- two of the three states that flipped between the parties between the 2000 and 2004 elections -- as well as Colorado and Virginia as the major battlegrounds of the 2012 election. And in light of the announced layoffs at Organizing for America, these states are important enough that FHQ would be willing to wager that no OFA scale back will affect any of the states listed immediately above.

The 2012-2020 Electoral College Map


[Click to Enlarge]

In view of the fact that the Census Bureau released its population numbers prior to the holidays, FHQ needs to issue a clerical change to its 2012 electoral college map; shifting from projection to reality. Not to beat a dead horse, but the take away is that the population in the purple to bluish states in the Rust Belt and northeast grew at a much slower rate (Michigan lost population) than red states in the southeast and purple to reddish states in the southwest. The seats in Congress shift accordingly. And while that appears to hypothetically swell the ranks of the GOP not only in the House but in the electoral college tally as well, that growth may be muted even in light of the gains the Republican Party made at the state legislative level in the 2010 midterm elections.

There was only a six electoral vote shift using the 2008 election results and the newly reapportioned map. Obama would have won 359-179 as opposed to 365-173. And the question remains whether Republicans at the state level will solidify through redistricting what they have in terms of current House districts or attempt to squeeze a few more seats out of the process while potentially opening the door to future electoral vulnerability in those races. We'll likely see a little bit of both strategies employed with the net effect that the GOP makes gains but not the extent that some of the doomsday scenarios that made the rounds following the 2010 "shellacking".

We'll have more tomorrow on the impact of these changes on the electoral college in 2012 and beyond, but for now the new map (especially in the sidebar for reference) will suffice.

UPDATE: Here's a look at the 2008 results using the 2012-2020 electoral college along with the electoral college spectrum and a look at the potential battleground states for 2012.

The Art of Redistricting

Maximize one's gains or solidify what one already has?

There have been a couple of good pieces I've read over the last couple of weeks that encapsulate the dilemma that faces those in control of the redistricting process.

Carl Bialik dips into the political science literature and finds while redistricting has an impact, it is limited by a host of factors.

Aaron Blake hits on some of the same themes, but does so through a case study of the dilemma facing Republicans in Texas.

Given the GOP's run through gubernatorial and state legislative races two weeks ago, the party has a distinct advantage in a series of states where they control the redistricting process. That said, those state governmental advantages may have a limited impact due to the question posed at the outset. The temptation of the former is tough to resist for any party that has unified control of a state government, but the latter is a pragmatic option that offers a safer and longer term effect. None of this is to suggest that the Republicans won't gain seats as a result of their victories on the state level. Rather, the point is merely to highlight the fact that parties with unified control of their state governments can only carve out so many additional districts for themselves before they begin to hurt the incumbents of their own party. That goes for Republicans and Democrats.

More Texas-less Fun

As long as we're messing with Texas...

Actually, since I put up a Texas-less version of the electoral college map in my post on the Texas frontloading bill last week, S.D. has been after me to do more with the map than just simply remove Texas. So, let's take those reapportionment numbers from FiveThirtyEight and put them into a map. And while we're at it, let's give Utah its fifth electoral vote back and bump the Beehive state up to 6 after the sans Texas reapportionment. [And no, I have absolutely no room to talk. Just take a gander at the comments to the electoral college by congressional districts post.]
[Click Map to Enlarge]

As Nate, said, the GOP is likely to lose ground on the presidential level, but gain at the congressional level without Texas on the map. But, I've got to admit that I can't just swipe those numbers and put them on my own map without making some original contribution of my own.

To wit...

What would happen in two years' time with the post-census reapportionment if Texas had in fact seceded from the United States? I'm glad you asked. It might look a little something like this (dark gray means seat gains, dark red equals losses):

[Click Map to Enlarge]

Based on the Election Data Services data I used to put together these post-2010 census maps, I reallocated each state's congressional seats without the Lone Star state. This reflects the projection based on the population changes witnessed between 2000 and 2008. Arizona, Florida and North Carolina are the beneficiaries of Texas' departure, gaining two seats apiece and the funny thing among the states that lose seats -- the usual Rust Belt suspects -- is that most of them, after gaining from the hypothetical Texas secession, revert to their pre-secession, pre-2010 census numbers. Ohio's back to 20 electoral votes. Pennsylvania's back to 21. New Jersey's back to 15. Michigan's back at 17. New York and Illinois luck out and actually gain a seat over where they are in reality now. The basic trend we are likely to see in 2010 is upheld here with or without Texas. The Sun Belt would gain electoral college clout at the expense of the states in the Rust Belt and stretching into the northeast.

For the sake of comparison...
Instead of the 389-147 win without Texas (pre-census), Obama would have managed a 381-155 victory over John McCain under the electoral college vote distribution of this map.

So no, I didn't resize the states to match their new electoral vote totals, but I think we'll have something to talk about regardless.

A Projected 2012 Electoral College Map (version 1.0)

For a look at the 2012-2020 electoral college map based on the 2010 Census click here. And for look at how those changes would have affected the 2008 presidential election click here.

There is no shortage of projections on how the 435 House seats will be reapportioned following the 2010 Census and like anything else, they range from modest changes to volatile, far-reaching changes. [And you can also see Nate Silver's attempts to update the 2007 projections -- the basis of both the linked projections above -- here.] What's funny is that both the links cite the same source, Election Data Services, yet describe very different projections. Well, the CQ article cites EDS while The Washington Times uses a combination of the EDS projections and those from Polidata. The Polidata end seems to be adding all the volatility. As such, I'm going to lean on the more conservative EDS projection (Silver's is in between but closer to EDS.).

[Alright, get to the point. How's the map going to look in four years?]

Well, here you go, complete with map and seat gains/losses:
[Click Map to Enlarge]

I jokingly ended the electoral college map slideshow with a blank map that had the election date of the 2012 election on it. But that one wasn't accurate; it didn't reflect the changes due to reapportionment that will happen between now and 2012. So what do we know about the changes? As all the articles that discuss the upcoming apportionment typically say, the South and southwest gain while the Rust Belt and into the northeast states continue to lose seats. But a blank map isn't really telling you a whole lot, is it? How about a real world application?

What would the McCain-Obama contest have looked like if this projected 2012 map was used instead? [Well, I made that one too.]

[Click Map to Enlarge]

McCain would gain three electoral votes on Obama and that is it. For the record, the Polidata projection, wacky as it is, would only yield McCain a few additional electoral votes. In a year that tilts toward the Democrats, those changes are manageable, but in a year with conditions triggering a more competitive contest, those changes might help the GOP. Then again, if the changes in Colorado and Nevada are lasting, Indiana, North Carolina and Virginia remain competitive, and Arizona and Georgia continue to trend toward the Democratic Party, they may benefit the Democrats.

UPDATE: One other way we can look at the changes more in-depth is to examine how that six electoral vote shift toward McCain in the projected 2012 apportionment changes the outlook on the Electoral College Spectrum. So, we can see how/if the campaigns' target states would have shifted if the map was different.

In September 2008, there was a time when Colorado or New Hampshire would have put Obama or McCain over the top in the electoral college. If Obama had won all the states favoring him up to and including Colorado the president-elect would have netted 269 electoral votes. The same was true of John McCain in terms of New Hampshire. Obama would have needed New Hampshire and McCain would have needed Colorado to cross the 270 electoral vote threshold. But Colorado eventually swapped positions with New Hampshire and moved into sole possession of the "victory line" distinction. To win Colorado, then, meant that the winner was the victor in the presidential race (...if they won the other states ranked behind the Centennial state).

Would that have been the case, though, if the 2012 map were in place for this past election?

The point between Colorado and Virginia is where Obama crosses (or McCain would cross) the 270 electoral vote threshold to win the presidential election. Obama would need Virginia and McCain would have needed Colorado to have surpassed that barrier. That line is referred to as the victory line. Under the actual 2008 electoral college distribution, Colorado was the state that each candidate needed to cross 270.

Well, no. That reapportionment-triggered shift toward McCain would have brought Virginia into the mix on the cycle's final Electoral College Spectrum. As was the case in the Colorado/New Hampshire situation, no one state would have been the Victory Line state. Instead, the possibility of an electoral college tie would have been put on the table. Both Virginia and Colorado would have to be won fo either of the candidates to pass the 270 electoral vote barrier. Of course, Obama won and held a six state cushion beyond that, but if the race had been, say, five or six points closer, Virginia would have been in play and the likelihood of an electoral college tie would have increased substantially.
