they truly are a conservative base

I understand that.

A Republican candidate that exhibits the antithesis of these values would not make it very far

I'm saying to bypass that. Force yourself onto their ballot by mobilizing Democrats to register as Republicans and then sign the petition to get you onto their primary ballot. Now your name is next to whichever actual conservative candidate came out of the Republican delegate voting.

And the Republican voters then get the primary ballot in the mail and see the two candidates and have no idea that one is actually a liberal masquerading as a conservative. There is no opportunity to "exhibit the antithesis."
