Santorum Clings to Lead In Michigan

Rick Santorum is holding a small lead over Willard Romney in the latest PPP poll, released just minutes ago. The final rundown is Santorum 38%, Romney 37%, Paul 14%, and Gingrich with 9%. PPP noticed a shift in momentum for Santorum with better polling numbers tonight than Saturday night. Another wild card in the race is the Democratic crossover vote for Santorum. Democratic Party leaders have begun robo-calling Democrats urging them to register Republican and vote for Santorum in this primary. For all the worry about Santorum losing the women vote he trails Romney by only two points; 37%-39%. Looking at the cross tabs another datum that jumps out is Santorum's appeal among 18-45 voters. He leads that demographic with 45 % which is 7% better than his overall polling numbers.
