The Republican caucuses were held on "Republican Party Precinct Caucus Day" (February 7, 2012).[1] Caucus locations opened on 9 PM, February 7, 2012,[2] with 36 delegates at stake; 33 of which are tied to the caucuses while 3 are unpledged RNC delegates.[3] The event occurred alongside the Minnesota Republican caucuses as well the Missouri Republican primary. The race was widely expected to be won by Mitt Romney even on the day of the caucus, but a strong surge by Rick Santorum across all three races that day carried him to a close victory. However, the delegates were not legally bound to follow voter preferences, and most voted for Romney.
The Colorado legislature adopted the caucus system in a special session called by Governor John F. Shafroth in August 1910 as part of a package of progressive reforms. It was seen as a way to limit the power of party bosses and to attract more grassroots involvement. The caucus system was abolished in favor of presidential primaries in 1992 but restored in 2002 with the defeat of Amendment 29[4] and cost considerations. The fully restored Colorado Caucus was in 2004.[5]
Polling in 2010 and 2011 showed mixed results, with Mitt Romney, Sarah Palin, Newt Gingrich being the favoured candidate depending on the poll. Polls leading up to election day showed Romney as the frontrunner.
There is no formal system of allocating delegates to candidates in any step of the election process. At each meeting the participants decides what the best course of action is. None of the 36 delegates are legally bound to vote for a candidate.[22]
12–13 April: Seven congressional conventions elects 3 National Convention delegates each and also elects delegates for the state convention.
14 April: State convention elects 12 National Convention delegates.
The Colorado caucuses were held on the same day as elections in Minnesota and Missouri. All three contests broke for Santorum. This was seen as undermining Romney's status as frontrunner.[24]
