These people we sickos. Ed gillespie is as mainstream as it gets for a GOP candidate. Sort of like colon Powell endorsing Obama over his old buddy McCain. They are disloyal fools.
John Warner has a rep as a vengeful and vindictive pr*ck. Gillespie probably did something to tick him off 20 years ago or so.
In fact, did Gillespie play some role in the Ollie North Senate Campaign back in 1994? Warner was FURIOUS about that, it would be the place I’d start looking for this being personal revenge rather than ideological.
