Tuesday 11 February 2020 (presumably): New Hampshire Primary. Hours reportedly 6:00a-8:00p EST (1100-0100 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 EDT 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 EDT and the networks have no problem considering this hour as the earliest hour of potential projection. Delegate Pledging: Proportional Primary. Voter Eligibility: Modified Primary.
