NBC NATIONAL NEWS — One of the closest, hardest-fought and most expensive presidential elections in history is coming to a conclusion.
President Barack Obama and former Massachusetts Governor Mitt Romney and their backers have spent a billion dollars to make their case and now the voters decide.
Mitt Romney voted in Belmont, Massachusetts this morning.
It marked the beginning of the the end of a grueling campaign, with high hopes for a key state: Ohio.
After casting his ballot Romney he headed off to Cleveland for one last effort.
President Obama, who'd voted two weeks ago, dropped by a volunteer office near his home in Chicago, where he called voters in the swing state of Wisconsin.
It's the last day of his last campaign.
"So I just want to say thank you to the American people," he told the crowd. "I also want to say to Governor Romney, congratulations on a spirited campaign. I know that his supporters are just as engaged and just as enthusiastic and working just as hard today."
Voter turnout seemed heavy.
Voters lined up at many polling places, some waiting for hours.
Their ballots will soon make history.
