MILWAUKEE - In one day, voters were set to go to the polls in the Wisconsin presidential primary.
Front-runner Mitt Romney was scheduled to return to Milwaukee while Rick Santorum would campaign in east central Wisconsin.
Romney's plans included a stop in Green Bay before heading to Moore Oil, on the 4000 block of West Custer Avenue in Milwaukee, to stump for last-minute votes ahead of Tuesday's primary.
"I want to become the nominee, not because I just can't wait to be in the White House, it's because I can't wait to get America back on track," said Romney at a rally on Sunday.
"Mitt Romney is ready, willing and able to lead our party and our nation," said Senator Ron Johnson.
Johnson and Janesville Representative Paul Ryan have each given their endorsement to Romney, with Ryan thought to be a possible vice presidential possibility.
One prominent Milwaukee Democratic state legislator sent a message of opposition about the front-runner on the Republican side.
"I want to make sure the public is not fooled by Mitt Romney and his message," said Sen. Chris Larson. "To be clear, this is a guy who thinks it's funny to joke about factories closing."
Meanwhile, as Santorum trails by double digits in polls including the most recent NBC News poll, and as he trails by a sizable margin in Republican convention delegates, he refuses to back down.
"When Gov. Romney gets that required number, then without a doubt, if he's at that number, we'll step aside," said Santorum on NBC's "Meet The Press."
"Right now, he's not there. He's not even close to it."
Santorum brought in some so-called star power while sweeping the state.
He brought the Duggar's, one of America's most famous mega-families, to cross Wisconsin with him.
"Santorum authored the bill to ban partial birth abortion in America. He's the true conservative," said Jim Bob Duggar.
Santorum was to make stops in Shawano, Menasha and Oshkosh.
Both Newt Gingrich and Ron Paul said on CBS's Face the Nation that they would not drop out of the race until they are forced to do so.
"I think we keep campaigning, and Gov. Romney has said he has to earn the 1,144 (convention delegates)," said Gingrich. We're not going to concede it to him."
"The votes haven't been counted," claimed Paul. "There's quite a few states right now. There's six or seven states where we're doing quite well through the delegate process, so we don't even know who's getting what."
Neither Gingrich nor Paul have events scheduled in Wisconsin on Monday.
