An election only puts a few people in an office. If those people try to exert their will through force (which, I wouldn’t classify cutting Harvard off as using force, just being a jerk) and there can be severe physical consequences done to the state for that action, then I wouldn’t call it a dictatorship at that point.
Most of my money is not in my wallet and I'm only wearing one of my many pairs of pants, but if someone stabs my wallet with a knife and puts a hole in my pants pocket, they are using force.
There are no consequences. The president has immunity and the courts are about to have the option of criminal contempt prosecutions removed. Cletus and his stockpile of ammunition are going to have little or no impact and he will be hunted down by law enforcement who are very much toeing the line.
The US regulatory system is intertwined with enough of the country that dictatorship can be wrought through its abuse.
E.g. if the US court system were more MAGA, Trump would be ignoring the Constitution today (habeas corpus), instead of toeing around the line
E.g. Trump silencing media speech by abusing FCC spectrum transfer authority
Institutions and the Constitution are what prevent the US from being a dictatorship, and ultimately both of those things rest on elected (indirectly or directly) officials, and therefore free and fair elections.
