Michigan Primary Tightens

A new Public Policy Polling survey in Michigan shows Rick Santorum leading Mitt Romney by just four points in the GOP presidential race, 37% to 33%, followed by Ron Paul at 15% and Newt Gingrich at 10%.

Key finding: “The tightening over the last week is much more a function of Romney gaining than Santorum falling. Santorum’s favorability spread of 67/23 has seen no change since our last poll, and his share of the vote has dropped only 2 points from 39% to 37%. Romney meanwhile has seen his net favorability improve 10 points from +10 (49/39) to +20 (55/35) and his vote share go from 24% to 33%.”
