All 41 of Massachusetts' delegates to the Republican National Convention are allocated to presidential contenders based on the statewide results of today's Presidential Primary.

• If a presidential candidate receives a majority (50% or more) of the statewide vote, that candidate receives all 41 delegates. [Plan for the selection of delegates Section 2.1.(a)]
• Otherwise, if 2 or more candidates receive more than 20% of the statewide vote, apportion the 41 delegates to those candidates receiving more than 20% of the statewide vote: Each candidates receives (votes for the candidate) ÷ (total votes for candidates receiving more than 20% of the vote). Rounding rules below. [Section 2.1.(b)]
• Otherwise, if only 1 candidate receives 20% or more of the vote, apportion the 41 delegates to the 2 candidates receiving the greatest statewide vote: Each candidate receives (votes for candidate) ÷ (total votes for the 2 candidates receiving the greatest statewide vote). Rounding rules below. [Section 2.1.(b)]
• Otherwise, apportion the 41 delegates to the candidates proportionally: Each candidate receives (votes for candidate) ÷ (total votes for all candidates). Rounding rules below. [Section 2.1.(c)]

Rounding: Beginning with the candidate receiving the most votes, round up any fractional delegates to the next whole number and proceed on to the next highest vote getter. Continue this until all delegates have been allocated. [Section 2.1(b)(c)]

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

The delegates are selected by the State Chair, State Committee, and Presidential campaign committee(s) according to the results of the primary. [Section 3.3(a)(b)(c)]

If a Presidential candidate who was entitled to delegates dies, withdraws, or changes party registration, delegates bound to that candidate will go to the National Convention unbound. [Section 2.3(b)]

Delegates are bound for the 1st roll call vote. [Section 2.3(a)]
