The parties only change when one of them just totally shits the bed. Then they’re usually replaced by a party that kind of does the same things but doesn’t seem to stink as much as the last one. Sometimes their opposition moves toward the center enough that the new party springs from their base instead.

At this point, the Democrats shitting the bed is very realistically the end of democracy, so instead of getting a shakeup and a New Left we’ll just end up with increasingly restrictive rules on who gets to participate in elections and increasingly questionable vote counting. But if you want to shake things up by just completely destroying the Republicans and hoping the Democrats (who are kind of suckers for “converting” Republicans) become the new conservative party, that I can get behind. The Republicans are already in shaky territory as they get more and more repulsive while dwindling in number. They’re dangerous because of that, but they legitimately could fall apart if they keep getting destroyed in elections while the diehards refuse to believe they need to change.
