Spoken in total ignorance. Both Falwell and Robertson were on the Bush bandwagon from an early stage and, to my knowledge, never uttered a peep of disastisfaction about issues with Bush during the campaign. I think they both kept a lower profile, in part so as not to be a lightning rod for Christian bashers out there who might otherwise have been attracted to Bush.
But there was no question that, too their own, they were publicly pro-Bush early - even while Bauer was running.
Falwell and Robertson both have their faults, but don't blaine them for being mad a Bush. They were both avid Bush supporters.
