Notes

Polling places in states that span multiple time zones will close either synchronously or asynchronously.

• (Note ^*S) With synchronized closing, all the polls close at the same GMT/UTC time. For states with multiple time zones-- when polls close in the advanced local time zone, they will close one hour earlier in the lagging local time zone.
• (Note ^*A) With asynchronous closing, the polls close at different GMT/UTC times in different parts of the state. Media outlets might decide to declare a winner before all the polls have closed.

Alaska Primary: Polls close asynchronously on Tuesday 19 August 2014 at 8:00p AKDT (0400 UTC) / 8:00p HADT (0500 UTC). Alaska Time covers most of the state except for the Aleutian Islands west of Umnak Island (approximately half of Aleutian Islands). The media considers Alaska's polls to close at 8 PM Alaska Time and, thus, considers the State "callable" after that hour.

Colorado Primary: Polls close synchronously on Tuesday 24 June 2014 at 7:00p MDT (0100 UTC). Colorado votes mostly by mail.

Florida Primary: Polls close asynchronously on Tuesday 26 August 2014 at 7:00p EDT (2300 UTC) / 7:00p CDT (0000 UTC). Relatively small portions of this state are in CT and so the vast majority of the polls are closed by the time indicated ET.

Hawaii Primary (makeup): Polls close synchronously on Friday 15 August 2014 at 6:00p HAST (0400 UTC). Damage caused by Tropical Storm Iselle resulted in the postponement of the primary in 2 Big Island precincts affecting about 8,255 voters.

Idaho Primary: Polls close asynchronously on Tuesday 20 May 2014 at 8:00p MDT (0200 UTC) / 8:00p PDT (0300 UTC). Local option allows polling places to open at 7 AM. A sizable part of IDAHO is in PT but, as the MT section is the much more populated portion of the state, the networks consider that "most of the polls in IDAHO" are closed by 8 PM MT.

Indiana Primary: Polls close asynchronously on Tuesday 6 May 2014 at 6:00p EDT (2200 UTC) / 6:00p CDT (2300 UTC). Although a portion of this state is in CT, the majority of the polls are closed by the time indicated ET when the networks feel they can project.

Kansas Primary: Polls close asynchronously on Tuesday 5 August 2014 at 7:00p MDT (0100 UTC) / 7:00p CDT (0000 UTC). For practical purposes, polling places open at 7 AM and close at 7 PM local time on Election Day. Technically, in the Central time zone, polling places open at 7 AM and close at 7 PM. However, a county may open the polls no earlier than 6 AM local time and close them no later than 8 PM. In the Mountain time zone, polling places open at 6 AM and close at 6 PM. However, a county may open the polls no earlier than 5 AM local time and close them no later than 7 PM.

Kentucky Primary: Polls close asynchronously on Tuesday 20 May 2014 at 6:00p EDT (2200 UTC) / 6:00p CDT (2300 UTC). Poll closing time could be rather problematic in KENTUCKY. A large chunk of the state is in Central Time [but the networks consider that "most of the polls have closed" in KENTUCKY by 6 PM Eastern Time and so, if they can, project at the same time they project INDIANA]. Central Time voters in KENTUCKY may note the networks' willingness/eagerness to project a winner as early as 6 PM Eastern Time.

Maine Primary: Polls close synchronously on Tuesday 10 June 2014 at 8:00p EDT (0000 UTC). Voting places open between 6:00a Eastern Time and 10:00a Eastern Time depending on the size of the town.

Massachusetts Primary: Polls close synchronously on Tuesday 9 September 2014 at 8:00p EDT (0000 UTC). By local option, municipalities may open their polls as early as 5:45 a.m.

Michigan Primary: Polls close asynchronously on Tuesday 5 August 2014 at 8:00p EDT (0000 UTC) / 8:00p CDT (0100 UTC). Relatively small portions of this state are in Central Time and so the vast majority of the polls are closed by the time indicated Eastern Time, when the networks feel they can project.

Minnesota Primary: Polls close synchronously on Tuesday 12 August 2014 at 8:00p CDT (0100 UTC). Voting begins at 10:00 AM in some townships.

Montana Primary: Polls close synchronously on Tuesday 3 June 2014 at 8:00p MDT (0200 UTC). A polling place with less than 400 registered voters must be open at least from noon to 8 p.m. or until all registered electors have voted.

Nebraska Primary: Polls close synchronously on Tuesday 13 May 2014 at 8:00p CDT (0100 UTC) / 7:00p MDT (0100 UTC). The polls open and close at the same GMT/UTC time, that is, polls open and close at a particular local time in the advanced time zone and open and close one hour earlier local time in the lagging time zone.

New Hampshire Primary: Polls close synchronously on Tuesday 9 September 2014 at 8:00p EDT (0000 UTC). Polls must open by 11 AM however most open between 7 AM and 8 AM. NEW HAMPSHIRE permits its 13 cities to keep their polls open until 8 PM Eastern Time by local option- however, as there ARE only 13 cities among New Hampshire's 234 County subdivisions [the 221 "non-cities", of course, being the proverbial New England Town(ship)], the fact is that the vast majority of NH's polls have closed by 7 PM Eastern Time and the networks have no problem considering this hour as the earliest hour of potential projection.

New York Primary: Polls close synchronously on Tuesday 24 June 2014 at 9:00p EDT (0100 UTC). Polls open at 6:00a in New York City and the counties of Nassau, Suffolk, Westchester, Rockland, Orange, Putnam and Erie. In all other counties, polls open at 12:00 noon. All polls close at 9:00p.

New York State / Local Primary: Polls close synchronously on Tuesday 9 September 2014 at 9:00p EDT (0100 UTC). Polls open at 6:00a in New York City and the counties of Nassau, Suffolk, Westchester, Rockland, Orange, Putnam and Erie. In all other counties, polls open at 12:00 noon. All polls close at 9:00p.

North Carolina Primary and CD12 Special Primary: Polls close synchronously on Tuesday 6 May 2014 at 7:30p EDT (2330 UTC). In extraordinary circumstances, the county board of elections may direct that the polls remain open until 8:30 p.m.

North Carolina Second Primary (CD5 D, CD6 R): Polls close synchronously on Tuesday 15 July 2014 at 7:30p EDT (2330 UTC). In extraordinary circumstances, the county board of elections may direct that the polls remain open until 8:30 p.m.

North Dakota Primary: Polls close asynchronously on Tuesday 10 June 2014 at 9:00p CDT (0200 UTC) / 9:00p MDT (0300 UTC). Voting places open between 7:00a to 12:00n and remain open until 7:00p to 9:00p depending on the size of the town. The western half of the state is in Mountain Time but that is, of course, the more sparsely populated part of the state, so it is not as problematic to the networks as might be otherwise suggested by simple geography. In 2012, polls closed at 8pm CDT in Cass County and at 7pm CDT or 7pm MDT in most other polling places.

Oregon Primary: Polls close asynchronously on Tuesday 20 May 2014 at 8:00p MDT (0200 UTC) / 8:00p PDT (0300 UTC). Oregon votes by mail. Ballots must be in the hands of election workers or in an official drop-off location no later than 8 PM local time. OREGON is the reverse of the norm because the by far largest portion of the state is in the lagging time zone and the networks have no choice but to not consider the OREGON polls closed until 8 PM Pacific.

Rhode Island Primary: Polls reportedly close synchronously on Tuesday 9 September 2014 at 8:00p EDT (0000 UTC). Most polls are open at 7am. However, polls may open as late as 9am by location.

South Dakota Primary: Polls close asynchronously on Tuesday 3 June 2014 at 7:00p CDT (0000 UTC) / 7:00p MDT (0100 UTC).

Tennessee Primary: Polls close synchronously on Thursday 7 August 2014 at 8:00p EDT (0000 UTC) / 7:00p CDT (0000 UTC). The polls close at the same GMT/UTC time, that is, polls close at a particular local time in the advanced time zone and close one hour earlier local time in the lagging time zone. Poll opening times are set by county.

Texas Primary: Polls close asynchronously on Tuesday 4 March 2014 at 7:00p CDT (0000 UTC) / 7:00p MDT (0100 UTC). Only the area around El Paso is in Mountain Time, so the vast majority of polls have closed in Texas by 7 PM Central Time.

Texas Runoff: Polls close asynchronously on Tuesday 27 May 2014 at 7:00p CDT (0000 UTC) / 7:00p MDT (0100 UTC). Only the area around El Paso is in Mountain Time, so the vast majority of polls have closed in Texas by 7 PM Central Time.

Vermont Primary: Polls close synchronously on Tuesday 26 August 2014 at 7:00p EDT (2300 UTC). Polls may open as early as 5:00a and no later than 10:00a as set by the Board of Civil Authority.

Washington Primary: Polls close synchronously on Tuesday 5 August 2014 at 8:00p PDT (0300 UTC). Washington votes by mail. Ballots must be postmarked on or before Election Day, or dropped off in a designated ballot box by 8 p.m. local time on Election Day.
