Trump is charismatic to low IQ and racist people and has a ton of propaganda being churned out on social media. Also right wing voters are more consistent getting out to vote and will almost always rally behind their guy. If gore had any personality he would have smoked bush who while not exactly charismatic he was someone people “could have a beer with”. Carter wasn’t very charismatic but probably the best person to hold the office and won on the back of Nixon and Watergate, much like Biden winning after Trump’s first term.
