Only three sitting US Senators have been elected President, and all three were bad.
This is for a simple reason. The President is the Chief EXECUTIVE. The main qualification for being a US Senator is being a bullshit artist.
These two roles - executive and BS artist - just don’t mix.
A Governor, high level businessman, or a military man are executive positions “worthy” of being POTUS.
Every senator thinks they can be president
Some actually believe they are president
