You gotta tell your county GOP, state GOP, and RNC. Call them, write them.
In my state when people register (or reregister) to vote they can officially self-designate as "no party preference," and late last year I re-registered to vote NPP after basically being a lifelong GOP voter (since the first time I voted back in the 1980s). I sent a copy of my voter registration confirmation postcard, showing the change, with a letter explaining why I was sending it, to my congressional rep, my county GOP, my state GOP, and the RNC. I told them forget about my vote. No more establishment GOP support.
They need to be told they screwed up.
They think we are dumb sheep who vote GOP the same way we eat, sleep, and sh!t: by habit.
If you donated money to the GOP before, or to GOP candidates, they have to know, not one more dime.
Do this. Do it now! I'm never voting for anyone in the UNI-Party who runs DC again. There's no difference between the Republicans and the Democrats. They are all corrupt. But if we all stop voting then they can stop pretending there are actually two parties when they are all NWO shills.
