“ Have to keep primarying the losers”
You presume you have a national majority to elect 218 Republicans willing to do what must be done, but you don’t.
Yes, it is possible to punish a representative or two by “primarying” him in a district that already is very conservative.
But there are not 218 such districts. There aren’t 100.
Voting is the problem, it’s not the solution.
Sorry you don’t see the same as me but I’m not any happier than you sbout the problems. I still think we can save the republic this way. It won’t be easy.
