That is OK to start out with your support. Then your support to shift to whichever conservative candidate is leading in delegate count after IA, NH, CO, UT, NV & SC primaries are over.
ALL other conservatives should drop out, and only the leading delegate winner stay in against Bush.
Note that now matter how good, a loser of nomination has zero power to change anything.

February 23 is the last chance date. If multiple conservatives remain after that, Jeb Bush will be your nominee because he has no one dividing RINO voters with him. Christy will not run.
