Recent polling showed momentum for President Obama heading into Election Day, but his campaign said that trend had nothing to do with the incumbent's choice to stay in his home state of Illinois today. GOP challenger Mitt Romney, by comparison, plans to make his final plea to voters with visits to Cleveland and Pittsburgh. 

Senior Obama campaign adviser Robert Gibbs said on NBC's "Today" show that the president chose to stay put and focus on a series of radio interviews to convince undecided voters to support him. 

"We felt the president would have a better reach to sit here and do some satellite interviews into states and make sure that the folks that we have out getting out our vote in important states aren't burdened by having to support him coming in to their state today," he said. "So I think we feel like we've got a great opportunity for the president to speak with still undecided voters in those nine battleground states today."

The president also made a surprise stop at a campaign field office in Chicago this morning to thank campaign workers and makle some last-minute calls to swing state voters, as well as to pay tribute to a hard-fought campaign. He congratulated Romney on "a hard-fought campaign." 

Senior Obama campaign adviser David Axelrod expressed strong confidence this morning that the president would win the election, citing recent polls and early-voting numbers. "The greater encouragement comes from the cold, hard data, which is that early vote in every battleground state that has early vote has been very robust in our favor," he said on CBS's "This Morning." "It is going to be a tight race, but we are either even or ahead in almost every one of these -- really every one of these -- battleground states."
