this party that has a “core belief about taxes, government and the Constitution” is largely a subset of the GOP.
“this party” isn’t large enough to completely dominate the GOP. If Pence, Cantor, etc. and the caucus they lead are not conservative enough for ya, I wonder who it is that you have recently helped get elected.
The fact that Snowe and Collins and others have an R after their name is just an indication that the conservative faction of the GOP is not as strong as some wish. Move to Maine and elect a conservative the House. Both House seats are available for the taking if someone can create a large enough following. (Or you can just run a Constitution candidate and lose 72% to 28% if that makes you happy.)
I'd call that a serious and fundamental showstopping problem.
Don't you?
If lower taxes, smaller government, and the United States Constitution are merely "a subset" of interest to the GOP, then why in the hell do you support the GOP?
That sounds completely nutty.
