Harry Enten notes that three Michigan polls from last Thursday found Mitt Romney leading Rick Santorum by an average of 5.7 points. However, Romney’s average lead in polls taken over the weekend is down to just 1 point.
Meanwhile, a Public Policy Polling survey in the field tonight is already picking up on “encouraging things for Santorum.” The full poll results will be out late tonight.
If true, it could be a late night tomorrow waiting for primary results to come in.
