Since there are no more conservative in the hunt, what makes you believe that?
Keep in mind that the RNC is liberal Washington Insider. It allowed open primaries to oust the conservatives.
We first need to take over the establishment from the inside then go from there.
Although I empathize with your comment, it was up to those conservative candidates to develop support.
If they can't get a decent percentage of votes from an open primary state, as the thinking goes, how can they expect to do well in the general election.
