In that scenario, each state delegation has 1 vote- and the GOP has enough state-level gerrymanders to control enough state delegations that if it comes to pass that the 12th Amendment process decides the presidency, they are very likely going to be able to install whoever they want.

I’m not so sure of this. On paper, the split is 27-23 in favor of Republicans. However, there are 3 Republican governors in Democrat states that voted for Biden: Nevada, Vermont, and New Hampshire. The question becomes whether those 3 Republican governors would override the votes of the people in their state and install Trump even though the voters voted for Biden? I’m not so sure any of them would want to go down in history as having effectively ignored the election and installing a dictator. I mean…they could. Anything’s possible. But if you’re a Republican governor in a Democrat state that voted for the Democrat nominee, do you really want to be the one to ignore that, essentially tell the public that their votes don’t matter, and install Trump as a dictator?

If all 3 Republican governors in Dem states honor the will of the people, it would essentially be a 26-24 split in favor of Democrats. Even if only two of the 3 states do, we’d end up in a tie. Either way, I don’t think that sending it to the governors would be a guaranteed win for Trump. Significantly more likely, yes. But a slam-dunk win? No. There would be absolutely enormous pressure on those 3 governors who would basically be deciding the election.
