Sure they do...Hillary ran twice. Obama ran twice. Bush ran twice. Clinton ran twice.
As far as I am concerned, when you raise your right hand and swear to "solemnly swear (or affirm) that I will faithfully execute the office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States." and you violate that oath, you are a TRAITOR.
Buh-bye
