Certainly not by me, but Sen. Lindsey Graham (aka. Sen. John McCain's roadie) is getting a fresh look from at least one media outlet as a potential running mate.
The sense is that McCain might go with someone that he trusts. And there are few politicians closer to the candidate than Graham.
I'm doubting it. This would be a Dick Cheney-esque move that, frankly, McCain can't afford. That said, maybe he just wants to pick someone he can chum around with on the bus.
