7:00 a.m.
Polls are opening across New Hampshire, though the exact hours vary from place to place.
State law requires polls to be open between 11 a.m. and 7 p.m. Tuesday. Most allow voting between 8 a.m. and 7 p.m., with a handful opening polls as early as 6 a.m. and about 20 remaining open until 8 p.m. And three tiny towns - Hart's Location, Dixville and Millsfield - had permission to open their polls at midnight and close them moments later once everyone had voted.
Independent voters, officially known as "undeclared," make up 44 percent of registered voters. They can vote in either primary, making them a key group on Tuesday.
