Procedure

Tennessee was given 58 delegates for the 2012 Republican National Convention. Three superdelegates were unbound. 27 delegates are awarded by congressional district, 3 delegates for each district. If a candidate wins two-thirds of the vote in a district, he takes all 3 delegates there; if not, delegates are split 2-to-1 between the top two candidates. Another 28 delegates are awarded to the candidate who wins two-thirds of the vote statewide, or allocated proportionately among candidates winning at least 20% of the vote if no one gets two-thirds.
