• If one candidate receives more than 50% of the vote or only one candidate receives 15% or more of the vote, that candidate receives 3 delegates.
• Otherwise, if exactly 2 candidates receive 15% or more of the vote, the candidate receiving the most votes receives 2 delegates and the candidate receiving the second most votes receives 1 delegate.
• Otherwise, if 3 or more candidates receive 15% or more of the vote, the top 3 vote-getters each receive 1 delegate.

• 25 at-large delegates (10 base at-large delegates plus 15 bonus delegates) are to be allocated to presidential contenders based on the statewide primary results.
• If one candidate receives more than 50% of the vote, that candidate receives all the at-large delegates.

Delegates are bound until released. "Each delegate ... to the national convention ... shall cast their vote on all ballots for the candidate ... If that candidate is ... no longer a candidate, the votes ... shall be cast for any candidate of their choice." [codified at 26 O.S. § 20-104 G.]

HB 1614 moves the Presidential Primary from the 1st Tuesday in February to the first Tuesday in March (6 March 2012). However, if one or more states sharing a boundary with Oklahoma sets a date for a regional primary, the State Election Board is authorized to change the date of the Oklahoma primary to the date of the regional primary, as long as the date is not before the first Tuesday in March. [OK Statutes 26-20-101]

Candidates for President of the United States must file with the State Election Board 5-7 December 2011.
