Good advice from Diana in Wisconsin:
Change your voter registration to Independent,
and make SURE your CongressCritters know it.

Just vote Rat, if you can’t beat ‘em, join ‘em, and let’s just blow up the illusion once and for all that there really is a choice.
If you’re in a closed or semi-closed primary state, affiliate with whatever party you want, but stay registered as a Republican and wreck havoc on their RINOs. Once they’re gone and the party is withered, then change your official affiliation.
BAD ADVICE.
It only dilutes your contribution to the cause. Contact your county republican party. Learn what they are doing. Support the actions that you feel will strengthen the positions you support. Help make your state strong and incorruptable.
