With television networks declaring an Obama victory, the Associated Press calls the hotly contested state of Ohio for Obama.

The Post's Craig Timberg reports from Cleveland:

Jubilation swept through a downtown hotel conference room here as networks projected that President Obama had won the battleground of Ohio and, as a result, re-election. But one of the Democratic Party revelers was not merely ecstatic. He was soaked, with his bald head dripping champagne.

“Baby, it’s not even midnight,” Andre Baird, 55, a retired Marine, exalted to a friend, “and it’s over!”

Party activists screamed and hugged. Some wept. Others exchanged toasts. Most chanted “Four more years!” Outside, cars honked. Passersby shouted their mixture of ecstasy and relief to friends on the other ends of cell phones.

A key to the victory here in Cuyahoga County, a Democratic stronghold where a large turnout is key to party victories statewide, was the heavy, highly organized voting by black voters, many of whom thought that some Republicans were determined to hold down the numbers of ballots cast by their community.

Baird, who is African American, said he did not see the campaign in strictly racial terms, but he had certainly noticed the tough going faced by Obama in his first four years, as he sought to revive a moribund economy amid allegations that he was not entirely American. Baird became a manic canvasser for Democratic votes in recent weeks, knocking on doors throughout his neighborhood in east Cleveland.

“It’ll be a few days before I come down,” said Baird, his voice hoarse as he shouted to be heard over the crowd. “These hands,” he added, making a fist with his right hand, "have knocked on at least a thousand doors.”
