Tbh, the 22nd Amendment was a bad idea imo. Term limits should be imposed by the electorate if they so choose, not by the Constitution. Regardless, I hope Trump is a one-term President, and definitely not a three-term President.
Eh, I disagree. One of the clear steps to know a country is heading towards dictatorship is the abolishment of term limits (or trying to do so). Just look at places like Venezuela (Chávez tried to abolish term limits in 2007 but failed; was later successful in 2009) or more reciently Bolivia (Evo Morales tried to abolish term limits in 2017 but failed; though that referendum was overturned reciently by the Supreme Court there iirc)
Repealing the 22nd Amendment would be one of the clearest steps towards making the US a dictatorship.
Just because countries without term limits can be dictatorships does not mean no term limits is necessarily a slippery slope to dictatorship. If someone is doing a good job they shouldn't be arbitrarily forced to leave office. FDR winning a third and fourth term was a good thing after all. There are plenty of long serving and successful democratic leaders.
