One problem is that, eventually, voters will want change. And when Democrats have been in charge of too many things for too long, even a Republican Party that has moved in a direction that many would describe as, well, deplorable will prove electable.
This is what we saw some of in California and Florida last year. California is dominated by Democrats and has been seen to be moving in an ever increasingly liberal direction. But in November, voters there reinstalled Republicans in a bunch of swing congressional districts.
In Florida, some Hispanic voters decided that if it was a choice between an authoritarian-inclined Republican Party or a Democratic Party with several high-profile, media-attention-grabbing members willing to proclaim themselves as socialists, they’d take the authoritarians.
I don’t want to leave the Republican Party. But I need to believe that if people like me stay, we will have a fighting chance at changing the direction of the party.
