When dozens of journalists and local voters can't get in to an event in a small town north of Des Moines, it's not hard to tell who has the mojo in a race for the White House, as former U.S. Senator Rick Santorum is enjoying a big boost in the polls here in Iowa.

"We have raised more money in the last few days than we have in the last few months," said Santorum during a morning stop at the Reising Sun Cafe in the small town of Polk City.

"I think we have the momentum here," Santorum told supporters, several of whom used the event to publicly tell the Pennsylvania Republican that he was their choice for the White House.

While Santorum was enjoying attention that he had never seen so far in his long shot bid for the White House, there were also big crowds on the trail for Ron Paul, who also thinks he has a good shot at a high finish on Tuesday in Iowa.

"I am encouraged, things are going well," Paul told a packed crowd at a conference center outside Cedar Rapids.

"There's a very good chance that we're going to do very well tomorrow night," Paul said, flanked by his son Sen. Rand Paul of Kentucky.

"If you believe in America and you believe in liberty and you believe in self-reliance, then we have to change the ways of Washington right now," Paul said to applause.

Think about this scenario - what if Paul and Santorum finish at the top - with Mitt Romney in third?

Would that shake up the GOP race?

Meanwhile, as for Newt Gingrich - I wasn't able to track him down on Monday, missing his admission to reporters that victory is not likely for the former U.S. House Speaker.

"I don't think I'm going to win Iowa," Gingrich said to reporters in Independence.

If you believe the polls, Gingrich could finish in fourth - just a few weeks ago, he was far ahead in the polls.

Now I'm off to find Rick Perry, wrapping up with a rally in Perry, Iowa; then I will wrap up Monday with a Romney rally in the suburbs of Des Moines.
