Much of the foofoora about John McCain's choice of running mate, Alaska Gov. Sarah Palin, seems to have an underlying unstated assumption for which I haven't seen the justification yet: that she was his first choice for a running mate. I don't have any particular reason to think she wasn't, but it grates on me to see all this talk that seems to just make the assumption, without any evidence cited.
And it would be amusing to think that maybe Mitt Romney, Joe Lieberman, and Tim Pawlenty had all been offered the slot, and fled from him like the proverbial rats from the ship, until he finally found a sucker willing to run as the sidekick's sidekick.
