Mitt Romney |
The 2012 Arizona Republican presidential primary was a closed primary that took place on February 28, 2012.[1] More than 1,130,000 registered Republican voters participated in the event, the purpose of which was to select delegates from the state to attend the Republican National Convention on behalf of candidates for the Republican presidential nomination. The Republican National Committee removed half of Arizona's delegate allocation because the state committee moved its Republican primary before March 6. Arizona therefore held a ballot to select 29 proportionally-allocated delegates. This election occurred the same day as the Michigan Republican primary. The Arizona primary was set as a winner-take-all contest, another violation of RNC delegate allocation rules, which require proportional allocation for all primaries held before April 1. Endorsements from 2008 primary rival and U.S. Senator John McCain[2] and Governor Jan Brewer[3] helped add to the prospects of a victory for Romney in Arizona.
