Barack Obama made history in 2009 when he became the first black president of the United States. Since then he's been described as the "first gay president" for his support of same-sex marriage. Now there's another first for the nation's 44th president.
Obama will be the first president in history to use early voting to cast his ballot.
The president told his 21 million followers on Twitter this week that he intends to use early voting to cast his ballot later this month. "I'm following @MichelleObama's example and voting early, on October 25. If your state has early voting, join me," Obama tweeted on Oct. 15.
Obama will be among an estimated 35 percent of voters in this year's presidential race to cast their ballots before Election Day on Nov. 6. The first lady used an absentee ballot to vote this week.
The first last, President Obama and Vice President Joe Biden have been encouraging voters to use early voting to cast their ballots in their race with Republican nominee Mitt Romney and running mate Paul Ryan.
Mrs. Obama told voters in Cleveland, Ohio, this week to vote early. "We want you all to vote early. All right? We want you to think about voting early, whether it's by mail or in person - vote early. Because when you vote early then you can spend that time on Election Day getting everyone you know out to vote," she said.
Early voting is underway in Ohio and other swing states including Virginia, Iowa and New Hampshire.
