The problem with hold one’s nose in November is that is exactly the strategy that has given us such a weak congress and dismal GOP-e.
So...the strategy will give us what? A Romney? Romney isn’t going to stop, repeal anything. Once he is in he is going to rollover like a good dog.
And the alternative is? Losing? That’s not an acceptable option. Realpolitics is winning as best you can with the best candidate for that election/district/etc. We can’t lose and get our country back.
