Adam Sorensen looks at the polling:

In the primary, it really looks like a wash. Public Policy Polling this week found a third of Republicans [in Michigan] say they’re more likely to vote for someone who opposed the rescue, compared to 27% who see it as a liability and 35% who say they don’t care. The general election numbers are different though. Obama leads the GOP field by around 20 points in Michigan, according to Marist, in part on strength derived from the popular auto bailout: 63% of voters say it was a good thing, including 42% of Republicans, and most think Obama deserves credit for the policy.

Know hope. There's sanity out there.
