Why do you think the GOP would have nominated a moderate?
Good question, and one I don't actually know the answer to if I'm honest (LOL). Perhaps the moderates would have taken over the Republican Party after the Neocons' choice of candidate, GWB, failed to secure the White House? Either way, I don't think they would have chosen GWB a second time. Choosing his brother Jeb would have aroused cries of "Dynasty!". Rumsfeld or Cheney lack the necessary mass appeal. The logical conclusion would have been Giuliani (easily one of the most popular politicians on the country after 9/11) or McCain (the most prominent Republican after the ones I just listed).
Like your new sig, btw.
