That West is "perplexed" that the GOP would try to stop an Republican nominated by Obama, shows her lack of intelligence. The GOP establishment is the war party, because they get lots of campaign cash from the military industrial complex (but not all of them, Hagel being one of the few). CATO, a libertarian organization, mostly associated with fiscal conservatives, endorsed Hagel as someone who supports reducing our meddling in foreign countries. The GOP war party can't have that. It would result in less campaign cash, and less war.
West doesn't know who our soldiers support. They supported Ron Paul and his foreign policy more than all the other candidates combined (and they supported him via individual campaign contributions).
