Not that I always interject on others squabbles, but what isn't to understand about this statement:
I don't know of any Republican in my area that was challenged in the primary that was an incumbent...What sandbar is saying is, he had no control over selecting conservative Republicans in the primaries because none of the incumbent Republicans were challenged by any conservatives!
If we can't get rid of the RINOs in the primary because they are not being challenged, then you have to get rid of them in the generals.
