One state to watch tonight is New Hampshire. The state is a presidential battleground, but its down-ballot races are similarly close, and could make history.
Female Democrats are vying for seats in three of the down-ballot races in the state. If they're all successful on November 6, New Hampshire would be the first state with a female governor, and an all-female Congressional delegation.
The first results out of the Granite State actually came in last night, in Dixville Notch and Hart's Location. But the bulk of the state's votes will start being tallied at 8 p.m. ET, when the polls close.
