With a strong, successful push over the weekend to move conservatives, especially social conservatives, back to him, Rick Santorum has re-taken the lead in the latest Mitchell/Rosetta Stone Poll of Michigan conducted for MIRS (Michigan Information & Research Service) Sunday night. The two front runners are still in a statistical dead heat, although Romney (35%) has lost his lead to Rick Santorum (37%) while Newt Gingrich (9%) and Ron Paul (8%) are locked in a battle for third place. Eleven percent remains undecided.
