I disagree with this, I think the Republican Party is waning and they’re now in the sweet spot where they have a large enough base to enact a fascist takeover but not enough to win by appealing to the electorate. If they aren’t able to change the rules in their favor in the next couple cycles I think they become further marginalized and lose their chance.
That’s not to say we won’t face a similar problem again after we have a party realignment, but I do think the GOP specifically has a limited window in which to seize power.
