There is no doubt that we need Constitutionalist conservatives to run for office, but they fight a losing battle when they have to fight against their own party as well as the Democrats. I have on several occasions seen good conservatives pretty much locked out by the GOP establishment in favor of the more ‘moderate’ candidates. It has gotten to the point that we have little to gain from affiliating ourselves with the GOP.
That is why Repubs with actual conservative ie Constiutionalist principles, and guts, need to take over the R party.
