> SCOTUS' ruling on Trump's presidential immunity blew a massive hole in the guardrails.
Not really; aside from the various limitations on it (full immunity only for a few core Constitutional functions, case-by-case immunity for other "official acts" depending on impact to function of the office, no immunity aside from that), criminal prosecution after leaving office is almost never the decisive constraint on Presidential action, and that's all the immunity applies to.
What blew a massive hole in the guardrails is the a faction fully supporting Trump being an authoritarian dictator unbound by law securing full control of the GOP, and the GOP securing a two-house Congressional majority. (It doesn't hurt that they also control a majority of state legislatures and a near majority of states both legislature and executive helps here, too.)
Yes, I agree that the Trump faction gaining control of the GOP is a huge problem and without it we'd be experiencing wannabe king Trump 1.0 instead of de-facto king 2.0.
But while technically you're correct, the implications of that ruling was that Trump could not be held accountable for the Jan6 attempted coup, giving him a huge boost to do whatever he wants with impunity. The significance was more psychological than technical. I don't believe we would see such bold power grabs by Trump if the SCOTUS had ruled against him.
Because it's clear the strategy now is 1) break all the rules; 2) let them sue; 3) if it ever makes it to SCOTUS our chances are decent, besides the fact that by the time it makes it through the courts to SCOTUS it will be too difficult to reverse what's been done. And in the meantime, use all the power of the Exec Branch to neutralize anyone who might oppose (legal firms, gov agencies, states, federal judges, etc.).
