WASHINGTON, DC -- Turnout remains heavy throughout the Potomac area today, and on both sides. At Stuart Junior High School on Capitol Hill, just a few steps from Politics Nation Plaza, about 500 Democrats had showed up to cast ballots by 1 p.m., an elections clerk said.

Surprisingly, in a city in which just 19,000 people voted for George W. Bush in 2004, the clerks at Stuart have already run out of Republican ballots. Election officials here said they hadn't expected so many GOP voters to turn out, which they said indicated heavy excitement on both sides of the aisle.

No polls have been conducted of Washington voters, but many assume John McCain will carry the city. Still, the plethora of churches in and around the city suggest Mike Huckabee might have a fighting chance.

On the Democratic side, Barack Obama spent part of the morning shaking hands with voters at Eastern Market and at a Dunkin' Donuts in a popular business district on Capitol Hill. Both Obama and McCain later made their way to the Senate floor, where Obama received congratulations from Washington State Senator Patty Murray, a Clinton backer. Obama carried all of Washington's 39 counties in his romp on Saturday.

Polls close in Washington tonight at 8 p.m.
