President Barack Obama is extending congratulations to rival Mitt Romney "on a spirited campaign." Obama says he's "confident we've got the votes to win."
Obama says he knows Romney supporters are "just as engaged, just as enthusiastic."
Obama spoke to reporters briefly after making calls to Wisconsin campaign volunteers Tuesday morning from a campaign office near his South Side Chicago home.
He said he and first lady Michelle Obama were grateful to all of the campaign volunteers who have worked hard on his behalf.
He was greeted by thunderous applause by about two dozen volunteers, many with tears streaming down their face.
During one call, he told a woman: "Hopefully we'll have a good day." And he told her to "keep working hard all the way through."
Early Tuesday in Massachusetts, Mitt Romney cast his ballot in the presidential election.
After all the flights, all the speeches, the debates, hand-shakes, nods, gestures and smiles, it was time for him to vote and then hold curtain-closing campaign rallies in Ohio and Pennsylvania. Then, he had to contemplate the fall of night and the counting of votes, and hope for the best.
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."
