Santorum, Romney close in Michigan

Mitt Romney and Rick Santorum are in a statistical dead heat in Michigan a week ahead of the vote, according to a new poll of Republican voters in the state.

Romney took 32 percent and Santorum 30 percent in a one-day poll of Michigan GOP voters by Mitchell/Rosetta Stone conducted on Monday. Romney's lead is within the poll's margin of error.

Former House Speaker Newt Gingrich (Ga.) trailed with 9 percent and Rep. Ron Paul (Texas) with 7 percent, but according to the survey 22 percent of those polled remain undecided.

The state, which votes in a week, on Feb. 28, has become a battleground for Romney and Santorum, who have changed places for the lead several times in the last two weeks. 

A Mitchell/Rosetta Stone poll released Feb 2. had shown Romney with a 15-point lead over the GOP field in the state.



But after three upset wins in Minnesota, Missouri and Colorado, Santorum surged to the top of the polls in Michigan and nationally. A Mitchell/Rosetta Stone poll on Feb. 14 showed Santorum at 34 percent support, followed by Romney at 25 percent.


But Romney, who has poured a million dollars of campaign money into the state, has doubled down on his expectation to win. Last week, Romney unveiled a new ad hitting Santorum over his record on earmarks. 

Romney is campaigning on home-state pride; he grew up in Michigan and his father served as governor in the state. He also carried Michigan in the 2008 GOP presidential contest, besting eventual nominee Sen. John McCain (Ariz.). 

The poll found that 25 percent of the voters surveyed are "more likely" to vote for him because he was born and raised in the state.
