You are trying to be pragmatic. That is not good. You are trying to compromise on ideology. That is also no good.
It is OK if democrats get elected in states like Delaware, Nevada, Colorado rather than getting RINO’s elected. So what if Reid is the majority leader and can call the shots on which bills can come to the floor. So what if if the majority leader in senate is not Republican. The main objective is to get rid of all RINO’s.
Conservatives can win in most places; it is simply about making sure those Conservatives are electable candidates.
