How Mitt Romney survived a near-death experience in Michigan.

For the last several weeks, Santorum has been inching toward becoming the conservative alternative to Romney. If that holds, the party split Romney barely survived tonight could continue to bedevil him. However, Super Tuesday will widen the race, and with it could mark the return of Gingrich, who believes he will do well in Southern states. If Gingrich rises again and keeps splitting the vote with Santorum, it could be a long summer with Santorum winning the Midwest, Gingrich the South, and Romney the states of any true size. If that’s the case, then this may not be the last time Mitt Romney’s campaign is born again.
