The majority of American voters can be as dumb as they want - the two big failures here are the legislature and the judiciary. The judiciary let an obviously illegal thing sit for far too long while the legislature is too partisan to actually take actions against the administration (except in the case of the Epstein files which has been surprisingly admirable and a rare ray of light in the last year).

If the majority of American voters elect snoopy the dog snoopy can do all of the things snoopy wants to do within the bounds of the law. Snoopy can use his bully pulpit to fight against dog restrictions in restaurants and grant pardons to previous offenders. Snoopy can ensure efficient spending of money on public water fountains accessible to canines... but if snoopy starts issuing open hand-outs to the red baron (snoopy in a moustache) that's when the other branches of government are supposed to step in - we aren't supposed to need to wait four years for the next election to stop open corruption (especially since corruption is really good at funding more corruption so there's a vicious cycle that can begin if you let it fester @see the recent FBI raid on GA election offices).
