I dunno. Run an angry, old coot liberal against a younger, charismatic liberal and it'll be like Nixon vs. Kennedy in 1960. Hell, McCain already looks as pasty white as something that crawled out from under a rotting log. Putting him next to the permanently-tanned Obama and people will do little but remark about how McCain looks like he's got one foot in the grave.
I agree on that. Just looking at him and Romney on the same stage yesterday made me think - OMG he looks bad - and looks matter esp in the TV age. Wait till he is next to Obama.
