Super Tuesday voting , after the early voting in February , decided nearly half of the delegate votes needed to achieve the 1,237 votes to win the nomination at the 2016 Republican National Convention — 595 delegates at stake , to be exact . Super Tuesday holds the primary voting for 12 states in the primary election process . North Dakota held the last caucus on Super Tuesday , but there was no presidential straw poll and all the delegates elected later at its convention in April were unbound . Wyoming took a straw poll , but it was non-binding and no delegates were allocated on Super Tuesday . Leading up to Super Tuesday , a debate between the remaining five candidates took place in Houston on February 25 , 2016 . Political rhetoric and charges heated up with Cruz and Rubio teaming up to attack Trump
