They were roommates at Harvard College actually. Did you know that? So I assume they have seen each other more than once or twice. Do they have much in common politically? Well, er, no. They might both diss Bush from time to time, but for very different reasons usually.
Regarding the 'commonality of politics'--we agree.....they're in 2 different worlds.
I always thougt it was possible that it was a "good cop" / "bad cop" kind of thing. Each of them peel away opposite sides of the Republican party and ultimately weaken the numbers of the party itself.
If one's goal was to benefit the opposition while pretending to be a disillusioned loyalist, the Kristol/Keyes tag team would be a perfect scam. Just a thought ???????
