In New York State’s Hudson Valley, voters decide today whether they will be represented in the U.S. House by State Assembly Minority Leader Jim Tedisco (R) or venture capitalist Scott Murphy (D). It will be a close election, with everything hinging on turnout.

Tedisco pulled an all-nighter last night, searching for last-minute votes in the region’s convenience stores and Wal-Marts. Helping him today is the fact that Tedisco supporters last week pulled an Obama — they challenged the petition signatures of the libertarian candidate, Eric Sundwall, and had him thrown off the ballot. (Sundwall retaliated by endorsing Murphy.)

The polls close at 9 p.m.
