Obama up by double digits in Mich.

The latest out of Michigan from Public Policy Polling shows President Obama with a 14-point lead over Mitt Romney, which hasn't moved much from the polling firm's previous findings there:

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 percent of voters consider him to be a Michigander to 65 percent who do not. And only 35 percent have a favorable opinion of him to 57 percent 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 percent of voters giving him good marks to 41 percent who disapprove, including a 50/43 standing with independents.

PPP also polled Michigan voters on their opinions of the ever-contentious political topic of the height of trees in the state, which Romney discussed on the trail earlier this year:

Much was made during the Michigan primary about Romney's comments about the state's trees being 'the right height.' That line seems to go over most voters' heads — only 38 percent express the sentiment that their trees are the right height while 8 percent think they are not and 55 percent are unsure. Democrats (48 percent) are actually more likely to express agreement with Romney on that front than Republicans are (34 percent).

In other words, Romney may be losing in the state overall, but at least he's got the tree-height vote...
