Not because of what you read but because of the Constitution which your orange fuehrer wipes his XXXL sized ass with every day. It's called an Amendment......to his toilet paper.
The law limiting U.S. presidents to two terms is the Twenty-second Amendment to the U.S. Constitution, ratified in 1951. It states that no person can be elected to the office of President more than twice, effectively prohibiting a third term for anyone who has been elected president twice.
