McCain still a stand up guy

How does he do it? McCain got bashed by the Clinton campaign and he shows up to see Bill in person, while Obama does the telecast. I never really appreciated McCain crossing the aisle like he does. It always seems like he gets taken advantage of, or used as a patsy. In this case he seems to gone out of his to do more than his competitor and shown himself as a leader above politics - or at least capable of it.
