The RINOs have had their powwow (and I bet Cornyn was there) and they decided they need to sabotage the Republican candidates to teach conservatives a lesson. They would rather have Democrats win than have their stranglehold of power threatened in the GOP.
Rove, Cornyn, Murkowski, Castle, Scozzafava, and Crist are all players.
They all have chosen to sacrifice themselves so other RINOs can live.
If the RNC or any spin-off tries to support Murkowski at this point, they are dust and no longer a national power.
They better start listening to the People because we are taking over. The RINOs can go pound sand and start their own party.
