Sunday 18 March 2012: Territorial Primary

20 of 23 of Puerto Rico's delegates to the Republican National Convention are bound to the presidential contenders based on the island-wide vote.

• If a Presidential candidate receives 50% or more of the vote, that candidate receives all 20 delegates.
• Otherwise, the delegates are allocated proportionally. (The threshold is apparently 15%. Rounding rules are not known.).

Delegates are directly elected on the primary ballot and are bound for the 1st ballot at the national convention. Voters may vote for as many as 20 delegates and can split their delegate candidate vote between candidates.[Article 8.021]

Gingrich has 20 delegate candidates; Karger 0; Paul 19; Roemer 0; Romney 20, and Santorum 0. In addition, there are 20 places for write-in delegate candidates.

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

Romney having won more than 50% of the island's votes, receives all 20 delegates.
