Mitt Romney has cast his ballot in the presidential election.

His wife, Ann, was at his side Tuesday morning when the pair cast their ballots near their Belmont, Mass. home a little before 9 a.m. EST. The Republican presidential candidate will return to Boston Tuesday night for an Election Day reception at the Boston Convention Center.

Asked who he voted for, Romney replied, "I think you know."

His running mate, Rep. Paul Ryan, is following a similar strategy, using his travel time after voting in his Wisconsin hometown to join Romney in Cleveland and then visit Richmond, Va.

The campaign isn't ruling out additional swing-state appearances as well.

Later, Ryan will await returns with Romney in Boston.

Meanwhile, President Barack Obama is back in Illinois to await results, telling voters at his final rally in Iowa the election is in their hands now.

He cast his ballot during early voting last week.

But the President's election night party will look far different than it did four years ago, when 125,000 people gathered on an unseasonably warm night in Chicago's Grant Park. The campaign decided not to test its weather luck this year and is holding the election night event indoors, at the McCormick Place convention center.

The decision appears to have been a smart one. The weather in Chicago on Tuesday night is forecast to be cold and rainy.

His running mate, Vice President Joe Biden, has cast his vote in the 2012 election, saying "it's always a kick."

Biden shook hands with and hugged other voters as he waited. He urged Americans to vote "even if you have to stand in line."
