I consider the candidate’s
viewpoints (he needs to believe in the same things I do), his
integrity (needs to be someone who is serving the public, not himself or his cronies), his
competence (has to understand the issues well enough to implement good programs to accomplish them), and his
leadership (needs to be able to get congress and the public behind his ideas).
Looking at viewpoints, he must be solidly pro-RKBA. If he is not, I weed him out from consideration. The candidates who meet the pro-RKBA litmus test can then be considered on the other issues and on their integrity, competence, and leadership.
If none of the candidates meet the pro-RKBA test, then I will probably pick the one likely to do the least damage to RKBA.
