This is the sort of thing that will destroy the tea party. Scott Brown was a compromise in the first place and now tea partiers there will have to do some soul searching and decide whether they will compromise again.
If it were me, I would probably vote for him but keep all references to the tea party out of it.
You and I agree on that. But, what a good stock of ammunition that gives the media in being able to say the tea party lost its way. Then again, it could prove that we are the one's willing to compromise for the greater good.
Run a Conservative Tea Party candidate against Brown in the primary.
