They don't need to learn a lesson, they need to be defeated. The GOPe is not an entity, but a group of individuals.
The RINO interlopers need to be taken out, one-by-one...NOT BY RATS...but by the TEAs. Otherwise, they should stay in place until that time comes.
You’re absolutely right that GOPe is a collection of loosely formed INDIVIDUALS. They are cowards when they attack TEA party and conservatives but as they “win” they become more bold. As they fail, they break ranks and run (ala Cantor).
A guy like Rove came up through the organized GOP structure being an in-house weenie nerd on state level and then national. He was discovered by Bushes as a good pollster, which helped Dubya become Governor of Texas. He has morphed into a bigger than life “architect” and “brain”. He is way above his competence.(Peter Principle).
We need to pressure RINOs and beat them one by one and quit giving money to organizations like Rove’s Crossroads.
We can right this ship.
