How can we as non-office-holders make that happen?
Lots of ways. Become an office holder, for one. Secondly, become involved in your county and state parties. Third, shift your dollars to organizations and/or people within the party that represent your view best. Fourth, realize that politics is the art of the possible and that pure ideology is not really possible in any organization--not even a family of three always has pure unadulterated agreement all of the time. Fifth, write (don't just email or call) your Senators and representatives in Congress. Sixth, write your state legislators who probably have more access to the feds than you do: when state legislators speak to them, they'll be saying the same thing about constituent attitudes that the feds see. Seventh, pray for the people making decisions.
Hope these suggestions help.
