There is no reason to abolish it, unless you prefer majority rule.

However, if you want a true republic and protection against the problems of majority rule, then you might want to potentially change it, but not abolish it.

The senate and modern house play that role.

As it stands, we have minority rule in nearly every branch of federal government.

The article I linked covered this topic.

The FEE argument, if assumed to be self-consistent, works even better as an argument against a status quo that systematically favors a minority party over a (popular) majority party.

If the goal is balancing power between political parties, then the presidency should certainly be a popular vote or else the house and senate should be substantially reformed.
