The first election results are in, from tiny Dixville Notch, New Hampshire. The village is famous for opening its polling place at midnight on Election Day and voting -and reporting the results immediately. This morning, ten citizens cast their vote, and in the presidential race, there was a tie: five votes each for President Obama and Mitt Romney. However, in Hart's Location, New Hampshire, which also opened the voting for just a short time at midnight, Obama got 23 votes and Romney received nine. Most polling places across the country will be open for a large part of the day, and results will not be announced until tonight. Link
To find out the polling hours and locations for your community, one handy resource is Vote411. You can enter your address and bring up exact information, with alternate links if you want to double-check. Or you can scroll down the sidebar and enter a state. I entered "New York" and found plenty of information and links about how voting will go on in the wake of hurricane Sandy. Link
