It could be as low as ~22% with the way the electoral college is set up. It’s unlikely but theoretically possible.
Winning with ~25% is possible with first past the post in equal population districts, so that’s no good either. It should be one person, one vote and whoever gets 50%+1 of the nation’s votes wins.
This particular topic would be best continued at Is the Electoral College still needed? We are at risk of going off topic again.
