Tuesday 13 March 2012: 37 of 40 of Mississippi's delegates to the Republican National Convention are allocated to presidential contenders in today's Mississippi Presidential Primary.

• 12 district delegates are bound to presidential contenders based on the primary results in each of the 4 congressional districts: each congressional district is assigned 3 National Convention delegates. [Rule 3]
• If one candidate receives a majority (more than 50%) of the vote in a Congressional District, that candidate is allocated all 3 delegates.
• Otherwise, each presidential candidate receiving 15% or more of the vote in that District is proportionally allocated delegates based on their percentage of the vote total of all candidates who met the 15% threshold.
• 25 at-large delegates (10 base at-large delegates plus 15 bonus delegates) are bound to presidential contenders based on the statewide primary vote. [Rule 4]
• If one candidate receives a majority (more than 50%) of the statewide vote, that candidate is allocated all 25 at-large delegates.
• Otherwise, each presidential candidate receiving 15% or more of the statewide vote is proportionally allocated delegates based on their percentage of the vote total of all candidates who met the 15% threshold.

Proportional allocation and rounding details: Round fractional proportions of a delegate to the nearest whole number. If rounding results in too few delegates being allocated, the candidate receiving the greatest number of votes receives an additional delegate. If rounding results in too many delegates being allocated, the candidate receiving the least number of votes looses a delegate.

National Convention delegates are bound until released by their candidate. [Rules 8 and 9]

In addition, 3 party leaders, the National Committeeman, the National Committeewoman, and the chairman of the Mississippi's Republican Party, will attend the convention as unpledged delegates by virtue of their position. [Rule 5]
