Romney's native state of Michigan is at best a second tier battleground state for now. Public Policy Polling has more:

Barack Obama won't have to worry too much about holding Michigan for the Democrats this fall- he leads Mitt Romney 53-39 there, a lead little changed from PPP's last poll of the state in February when his advantage was 54-38.

Romney just doesn't have much of a home field advantage in the state. Only 24% of voters consider him to be a Michigander to 65% who do not. And only 35% have a favorable opinion of him to 57% with a negative view.

It's not just Romney's unpopularity helping Obama in Michigan though. Obama's own approval rating is at a record high in our polling of the state with 53% of voters giving him good marks to 41% who disapprove, including a 50/43 standing with independents.

Obama's crushing Romney on what will doubtless be one of the biggest issues in the campaign in Michigan- 55% think that he's been better for the automotive industry in the state to only 31% who say Romney wins out on that front.

Going inside the numbers Obama's winning over 13% of Republican voters while losing just 7% of Democrats, and he also has a double digit advantage with independents at 48-36. Obama's winning women by a 58-34 margin and significantly has a 10 point lead with white voters at 50-40.

Things may get closer in Michigan between now and November but Obama has a lot of breathing room and looks pretty safe to take the state again, regardless of Romney's local connections.
