The field continues to shift in the race for the Republican presidential nomination as former Massachusetts Gov. Mitt Romney and former Pennsylvania Sen. Rick Santorum battle for the top spot in the Michigan and Arizona primaries.
The polls in those states open in less than 24 hours, and they'll be key to the momentum going into Super Tuesday, Mar. 6.
Romney originally lost the lead in his home state of Michigan, but now polls show he's fought his way back and is virtually tied with Santorum.
"I'm planning on winning here in Michigan and also in Arizona," Romney said. "Obviously, that will be huge for us if we're able to, particularly having come from so far behind here in Michigan."
He added that "the momentum is in the right direction."

Santorum doesn't appear to be concerned. He made an appearance at the Daytona 500 in Daytona Beach, Fla., on Sunday to see his NASCAR nation billboard car.
Before the race was rained out, Santorum said he advised the driver to use his campaign strategy.
"I'm hoping that for the first, you know, maybe 300, 400 miles, he's sitting way, way back, letting all the other folks crash and burn, and then sneaks up at the end and wins this thing," he told ABC News.
Political experts worry that a Santorum win on Tuesday could be devastating for the Romney campaign. They say the American people won't have much use for a front-runner who can't even win his home state.
Some are concerned Santorum's controversial statements about contraception, prenatal care, and the role of religion in public life will alienate independents.
On Sunday he defended his remarks that John F. Kennedy's speech on religion and politics made him want to "throw up."
"I believe in an America where the separation of church and state is absolute," Kennedy said in a speech to Baptist ministers in Houston in 1960.
"'People of faith have no role in the public square?' You bet that makes you throw up. What kind of country do we live in where only people of non-faith can come in the public square and make their case? That makes me throw up," Santorum explained.
Fellow candidate Newt Gingrich appeared to agree. Speaking at a Georgia church, the former House Speaker said people with a radical secular agenda are trying to destroy America's religious foundation.
"We have a secular elitist wing that deeply, deeply disbelieves in America, that wants to create a different country based on a different set of principles," he said.
New Jersey Gov. Chris Christie said the Republican presidential race could end up in a contested party convention this summer.
Christie said right now all voters can do is wait and let the process work its way out.
