This year Trump has no credible challenger,and after Super Tuesday there won’t be a way to mount one. In my state we don’t have any contentious congressional primaries. Next year will be another year.
I agree with your statement for states where we havea chance to remove an old bushbot or replace a crappy Governor.
Grassroots should be involved in the party process every single year. That’s how we make sure we have good leadership when we need it. Congress nominations, electors, RNC delegates, local offices, party positions including unit chairmen, all still in play.
