The most recent Des Moines Register poll shows former Massachusetts Governor Mitt Romney in a statistical dead heat with Texas Congressman Ron Paul, though former Pennsylvania Senator Rick Santorum is edging towards the top.

Romney is considered a more moderate Republican, while Paul has a large number of Libertarian supporters and favors an isolationist foreign policy.

Instead of going after his rivals, Romney has been attacking President Barack Obama at rallies, saying he is the Republicans' best chance to win in November.

"The president seems to want to turn us into a European-style welfare state, with an entitlement society where government comes to take from some people to give to others," Romney said. "What will that do? That will replace ambition with envy."

At a rally in Des Moines, Paul said he is offering something different from the other Republicans.

"Tomorrow is a very important day, small in numbers, but a very big message," Paul said. "So you carry a lot of weight in this state, to send a message on which way we're going. For the status quo — believe me, you don't have to worry about the choice if you choose another candidate, because the others represent the status quo."

Meanwhile, Santorum, considered a favorite among evangelical Christians, campaigned today in Perry, Iowa to try to unify socially conservative voters.

He told NY1 that he expects to be an electable candidate in the general election.

"When every pundit and every expert goes out there and says, 'he's the most electable,' it's been said for probably the last three or four years, that people listened to that, and I saw this all the time," said Santorum. "People would say, 'Well Rick, you're not electable,' and then they finally said, 'Why am I listening to these folks, whether he's electable?'"

Former front-runner Newt Gingrich, the former speaker of the House of Representatives, told supporters at an event today that he did not expect to win Iowa, blaming the "volume of negativity" in recent days.

Finally, Minnesota Representative Michele Bachmann released her first and only campaign ad today, reminding voters of her Iowa roots.
