Jonathan Martin of Politico is reporting that John McCain is pulling out of Michigan.

I will now put forward what I believe is the least likely explanation of why McCain is pulling out of Michigan:

1. Former Congressman and Edwards campaign manager David Bonior is from Michigan.
2. Bonior was very public in expressing his disappointment in John Edwards following it was revealed he’d had an affair.
3. Black hole magic step.
4. McCain is pulling out of Michigan.

I challenge you to find a less likely explanation for why McCain is pulling out.
