Hoekstra's decision to run certainly gives Republicans a credible candidate in this race. But he's still a long shot and if he wins it's likely going to be the product of a Republican landslide year that results in the party coming away with something in the neighborhood of 55 Senate seats.
Think about it this way- Stabenow is stronger in the state than Barack Obama is. Obama won Michigan by 16 points in 2008- he would probably need to shift about 20 points in the wrong direction, losing the state by 4-6 points, to pull Stabenow down with him. Obama's numbers aren't very good right now but they haven't plummeted to that point.
