The '''SEC primary''', also called "Super Tuesday" because of its size, consists of eight southern states (and a few northern states like Vermont) holding their presidential primary on the same day, March 1, 2015. The name comes from the popular southern football conference. It is called "Super Tuesday" because more than 500 delegates are at stake. | The '''SEC primary''', also called "Super Tuesday" because of its size, consists of eight southern states (and a few northern states like Vermont) holding their presidential primary on the same day, March 1, 2015.
