Specifically what races do you see this happening? In the Senate, there are no RINOs that are going to be replaced by conservatives. If Laffey beats Chafee in the RI primary, we will have a liberal representing RI in the Senate instead of a RINO. In Chafee's case (ACU rating =12) that is fine with me. But there are no other Senate races where there is a conservative still running against a RINO.
Your efforts are too late to effect the 2006 races, except to elect liberals.
It could happen in any race with a Constitution Party candidate. It's too late to do something about 2004 (or 2005), but it's not too late to do something about 2006 until November.
