The GOP race for president has flipped in Wisconsin since last month, with Mitt Romney overtaking Rick Santorum in the latest poll by Marquette Law School.

Romney leads Santorum 39% to 31% in a survey of GOP primary voters taken last Thursday through Sunday.

Ron Paul is running third in the poll with 11%, followed by Newt Gingrich with 5%.

The new numbers represent a major shift from Marquette’s February poll, which showed Santorum leading Romney in the state 34% to 18%, followed by Paul at 17% and Gingrich at 12%.
