WRONG! Only in the delusion of your own heads do you think you have those types of numbers. The number of dunces who insist on a purity are actually quite low, as evidenced by the voting numbers for idiots such as Bob Barr, Ron Paul, Chuck Baldwin, etc.
If McCain had picked a Liberal woman like Christine Todd Whitman or Elizabeth Dole or even a Liberal man like Giuliani or Ridge he wouldn't stand a chance.
So, yeah, you can thank us hard-headed, rock-ribbed, no-nonsense, damn-the-torpedoes-full-speed-ahead Conservatives for causing McCain to pick Sarah Palin.
