- Several caucus states have yet to select a date for the first step of their delegate selection processes in 2012. Until a decision is made by state parties in those states, they will appear in gray on the map.
- The states where legislation to move the presidential primary is active are two-toned. One color indicates the timing of the primary according to the current law whereas the second color is meant to highlight the most likely month to which the primary could be moved. [With the exception of Texas, the proposed movement is backward.] This is clear in most states, but in others -- Maryland and Tennessee -- where multiple timing options are being considered, the most likely date is used. Here that is defined as a bill -- or date change -- with the most institutional support. In both cases, the majority party leadership is sponsoring one change over another (February to March in Tennessee and February to April in Maryland). That option is given more weight on the map.
- Finally, Kentucky is unique because the legislation there calls for shifting the primary from May to August. As August is not included in the color coding, white designates that potential move with the May shade of blue.
- Caucus states are italicized while primary states are not. Several caucus states are missing from the list because they have not formalized the date on which their contests will be held in 2012. Colorado appears because the caucuses dates there are set by the state, whereas a state like Alaska has caucuses run by the state parties and as such do not have their dates codified in state law.
- States that have changed dates appear twice (or more) on the calendar; once by the old date and once by the new date. The old date will be struck through while the new date will be color-coded with the amount of movement (in days) in parentheses. States in green are states that have moved to earlier dates on the calendar and states in red are those that have moved to later dates. Arkansas, for example, has moved its 2012 primary and moved it back 104 days from its 2008 position.
- The date of any primary or caucus moves that have taken place -- whether through gubernatorial signature or state party move -- also appear in parentheses following the state's/party's new entry on the calendar.
- States with active legislation have links to those bills included with their entries on the calendar. If there are multiple bills they are divided by chamber and/or numbered accordingly.
- Iowa, New Hampshire and South Carolina appear twice. The earlier entry corresponds with the latest possible date these states would have if Florida opts not to move their primary into compliance with the national party rules. The second, later entry for each of the non-exempt states reflects the position the national parties would prefer the earliest states to hold their delegate selection events.

1 New Hampshire law calls for the Granite state to hold a primary on the second Tuesday of March or seven days prior to any other similar election, whichever is earlier. Florida is first now, so New Hampshire would be a week earlier at the latest. Traditionally, Iowa has gone on the Monday a week prior to New Hampshire. For the time being we'll wedge South Carolina in on the Saturday between New Hampshire and Florida, but these are just guesses at the moment. Any rogue states could cause a shift.
3 In Arizona the governor can use his or her proclamation powers to move the state's primary to a date on which the event would have an impact on the nomination. In 2004 and 2008 the primary was moved to the first Tuesday in February.
4 Massachusetts and Michigan are the only states that passed a frontloading bill prior to 2008 that was not permanent. The Bay state reverts to its first Tuesday in March date in 2012 while Michigan will fall back to the fourth Tuesday in February.
5 The Colorado Democratic and Republican parties have the option to move their caucuses from the third Tuesday in March to the first Tuesday in February.
6 The law in New Mexico allows the parties to decide when to hold their nominating contests. The Democrats have gone in early February in the last two cycles, but the GOP has held steady in June. They have the option of moving however.
