MILWAUKEE (AP) -- As voters head to the polls today in Wisconsin, Maryland and the District of Columbia, Mitt Romney is giving a subtle push to rival Rick Santorum to leave the race.
Romney told Fox News that the "right thing" for Republicans is to get a nominee as soon as possible, and "be able to focus on Barack Obama."
He said that when Ross Perot ran as an independent in the 1992 general election, it allowed Bill Clinton to defeat President George H.W. Bush.
Romney has one campaign event today before an election night party in Milwaukee. He spent the weekend campaigning across Wisconsin in the company of Rep. Paul Ryan.
Santorum is spending the day in Texas at private fundraisers before heading to his home state of Pennsylvania.
Romney and President Barack Obama are already acting as if the November matchup is set. Obama's re-election campaign is running a new TV ad targeting Romney, while Romney says his campaign will continue to focus on the president.
