Poll: Santorum’s Michigan Lead Down to Four

ST. CHARLES, MO - FEBRUARY 7: Republican presidential candidate, former U.S. Sen. Rick Santorum speaks to supporters as his daughter, Elizabeth (L), and wife, Karen (R), look on February 7, 2012 at the St. Charles Convention Center in St. Charles, Missouri. According to early results, Santorum defeated former Massachusetts Gov. Mitt Romney, former Speaker of the House Newt Gingrich and U.S. Rep.

PPP's latest Michigan data shows that the race for Romney's old stomping ground probably won't be a Santorum runaway on Tuesday, February 28. Santorum is still the choice of 37 percent, compared with 33 percent for Romney, 15 percent for Ron Paul, and 10 percent for Newt Gingrich. But that's a large shift from only a week ago when Santorum led Romney by 15. With Santorum's favorability spread and vote share nearly unchanged, PPP finds that the shift had everything to do with Romney, and apparently nothing with Santorum or his wealthy backer's modern-day contraception solution.
