But wait! There's more!
If Palin is Roslin, isn't McCain very much a Bill Adama? Both are Navy men. Both seemed destined to be passed over by a younger generation of hotshots, until a perfect storm elevated them to command. Both are tough old dogs with little patience for politics. Heck, Adama's staff even call him the Old Man.
Like Adama and Roslin, McCain and Palin should complement each other well. I eagerly await the moment in the VP debate when Palin is asked what she would do with Osama bin Laden if he were captured. One assumes her answer will be some variation of, "Put that thing out the airlock."
* Galley Wife S.L. observed this within seconds of Palin stepping on stage.
Update: Several astute commenters make the point that it's really more of a Tigh-Roslin ticket. I can buy that for a couple reasons: (1) The uncanny physical resemblance of McCain and Tigh; (2) Both McCain and Tigh were POWs; (3) McCain is reputed to have a temper somewhat approaching the Irish of Saul Tigh.
All of that said, in defense of seeing McCain as Adama, I'd argue that (1) Tigh is fundamentally, Adama's guy; McCain is his own man, for better or for worse; (2) Both McCain and Adama were hot-shot fighter jocks; (3) Most strikingly, Adama's Maverick-Streak
Also, McCain wouldn't resent Kara Thrace; he'd totally dig her.
