WASHINGTON — President Barack Obama won the reliably Democratic Northeast, and Republican Mitt Romney secured his Republican conservative base Tuesday night in a tense duel for the White House shadowed by a weak economy and high unemployment.
The critical battlegrounds with the key to victory were unsettled — Virginia, Ohio and Florida among them — with long lines in many locations after poll-close time.
Romney led in the national popular vote with 13 million votes, or 51 percent, to 12 million or 47 percent for Obama, with 10 percent of the precincts tallied.
Romney also held an early electoral vote advantage, 153-123, with 270 needed for victory, although he lost both his home state of Michigan and Massachusetts, where he served one term as governor.
The economy was rated the top issue by about 60 percent of voters surveyed as they left their polling places, but more said former President George W. Bush bears responsibility for current circumstances than Obama does after nearly four years in office.
About 4 in 10 said the economy is on the mend, but more than that said it was stagnant or getting worse more than four years after the near-collapse of 2008. The survey was conducted for The Associated Press and a group of television networks.
Polls were still open in much of the country as the two rivals began claiming the spoils of a brawl of an election in a year in which the struggling economy put a crimp in the middle class dreams of millions.
The president was in Chicago as he awaited the voters' verdict on his four years in office. He told reporters he had a concession speech as well as victory remarks prepared. He congratulated Romney on a spirited campaign. "I know his supporters are just as engaged, just as enthusiastic and working just as hard today" as his own, he added.
Romney reciprocated, congratulating the man who he had campaigned against for more than a year.
Romney raced to Ohio and Pennsylvania for Election Day campaigning and projected confidence as he flew home to Massachusetts to await the results. "We fought to the very end, and I think that's why we'll be successful," he said, adding that he had finished writing a speech anticipating victory.
Voters also chose a new Congress to serve alongside the man who will be inaugurated president in January, Democrats defending their majority in the Senate, and Republicans in the House.
In Maine, independent former Gov. Angus King won a Senate seat long in GOP hands, the first potential switch of the evening. He has not yet said which party he will side with, although Republicans attacked him during the campaign with television advertising, and Democrats rallied to his cause.
The long campaign's cost soared into the billions, much of it spent on negative ads, some harshly so.
In the presidential race, an estimated one million commercials aired in nine battleground states where the rival camps agreed the election was most likely to be settled — Ohio, New Hampshire, Virginia, Florida, North Carolina, Wisconsin, Iowa, Colorado and Nevada.
In a months-long general election ad war that cost nearly $1 billion, Romney and Republican groups spent more than $550 million and Obama and his allies $381 million, according to organizations that track advertising.
In Virginia, the polls had been closed for several minutes when Obama's campaign texted a call for volunteers "to make sure everyone who's still in line gets to vote."
In Florida, there were long lines at the hour set for polls to close. Under state law, everyone waiting was entitled to cast a ballot.
According to the exit poll, 53 percent of voters said Obama is more in touch with people like them, compared to 43 percent for Romney.
