Though the Club for Growth could prove me wrong, I'm not terribly optimistic that anything will happen to the eight Republicans who voted for cap and trade. Two of them -- Mark Kirk in Illinios and Michael Castle in Delaware -- are being recruited to run for Senate seats, a promotion of sorts. The polling and the need for pickup opportunities make recruiters unlikely to change their minds. If Castle decides against a Senate run, Republicans would fear losing his House seat if they ran any candidate other than him.
