Details of GOP delegate allocation

Each state has its own method for allocating delegates. Some will award them according to the proportion of the vote each candidate gets, some will give them all to the winner, and some will award many of their delegates by the candidates’ performance in each of a state’s congressional districts. There are 2,286 delegates up for grabs in 2012, after some states lost half of their delegates for setting their contests too early (in violation of Republican National Committee rules), and a candidate needs 1,144 delegates to win the GOP presidential nomination.
