Well that's a bit strong. Hewitt is truly a conservative.
OTOH you are correct, I believe, about his influence. Hewitt tends to be overly optimistic about the chances of the candidates (and the party) he supports and this leads me to discount anything he says including this article.
I used to listen to Hewitt and Medved in the afternoons out here on the Left Coast. No longer. Medved is pimp for McPain, Hewitt is not to be believed and they both run so many commercials and breaks for the weather and traffic that there just isn't any continuity to their shows any longer.
For me it is Rush and FR.
Hugh went hard for Mitt early on knowing the strategy of the Republican establishment was for McCain. Mitt was hardly a conservative and the split with the social conservatives lent an opening for McCain to walk through. Conservatives were already apprehensive about Mitt.
