He is indeed the best type of conservative, a conservative Christian and I would vote for him and a few others the rino GOP has chosen to disregard and even lie about in their support of the left leaning Rudy,Mitt, and John.
But you know rinos, they are social liberals and also march in lockstep while complaining that conservatives won’t support their candidates, they are the ones who will lose this election by running a rino candidate.
Huckabee may be a Christian, I'n not qualified to make a judgement on that question, but he is certainly no conservative.
So vote for him if you want, but please don't allow yourself the comfortable fiction that you would be voting for a conservative. You would not be.
