Until actual functioning safeguards are put in place, there's no reason to assume the US will stop being vulnerable to bad actors
like the GOP abusing their power.
Yeah, kinda a "time for foundations level constitutional upgrade" situation. Happens to nearly all countries at some point and frankly certain frequency. Constitutional rules aren't fit for purpose anymore due to times and circumstances having changed massively and it leads to dysfunctions and problems.
After all the current one is realistically the nations 2nd constitution, so why not move to a 3rd one. First lasted couple decades, second couple centuries. That is a good run, but there is nothing that exceptional about country deciding "Problems and casting faults noticed. its time for rewrite, convene the constitutional conference and let's get to work".
