In the Constitution of the United States, there is an explicit prohibition on a second term for the president of the U.S. There is no such thing as a "free vote" in the Constitution, but the power of the president to change the law is not unlimited.

The only president who has ever been re-elected is George W. Bush, who was elected in 1996. The current president, Barack Obama, was elected on a platform of ending the use of violence against women. He is the first president to be re- elected since George H.W. Bush in 2000.
