They.....define "they".

We are citizens of a representative republic.

There are 537 people in Washington D.C. who we elect to represent us, either through a direct vote or the electoral college.

The President, constitutionally, has no more power than Congress or the SCOTUS. In reality, the Presidency is a rather weak executive office.

Don't like what's going on? Your vote against your incumbent congressional representatives will have far more effect than any vote for the oval office. Nothing will change while the incumbency rate in Congress remains in the 90% range.
