February 25 , 2016 – Houston , Texas After the caucus in Nevada , the tenth debate was held at the University of Houston in Houston and broadcast by CNN as its third of four debates , in conjunction with Telemundo . The debate aired five days before 14 states vote on Super Tuesday , March 1 . While the debate was to be held in partnership with Telemundo 's English-language counterpart NBC , RNC Chairman Reince Priebus announced on October 30 , 2015 , that it had suspended the partnership in response to CNBC 's " bad faith " in handling the October 28 , 2015 , debate . On January 18 , 2016 , the RNC announced that CNN would replace NBC News as the main host of the debate , in partnership with Telemundo and Salem Communications ( CNN 's conservative media partner ) . The debate was shifted a day earlier at the same time . '' National Review '' was disinvited by the Republican National Committee from co-hosting the debate over its criticism of GOP front-runner Donald Trump . On February 19 , the criteria for invitation to the debate was announced : in addition to having official statements of candidacy with the Federal Election Commission and accepting the rules of the debate , candidates must have received at least 5 % support in one of the first four election contests held in Iowa , New Hampshire , South Carolina , and Nevada . By these criteria , all five remaining candidates , Carson , Cruz , Kasich , Rubio , and Trump , qualified for invitation to the debate . The 155 delegates to the Republican National Convention were allocated in this way . 108 delegates are allocated by congressional district ; 3 per district . If a candidate gets over 50 % of the vote in a congressional district ; they would win all of the district 's 3 delegates . If no one had a majority and one candidate had at least 20 % of the vote , the candidate winning the plurality would get 2 delegates and the candidate in second place would get 1 delegate . If nobody receives at least 20 % of the vote , the top 3 vote-getters each get 1 delegate . There were another 47 at-large delegates . If someone received more than 50 % of the vote , they would get all of the at-large delegates . If no one got more than 50 % of the vote and there were at least 2 candidates that got over 20 % of the vote , the delegates would be allocated proportionally among the candidates receiving more than 20 % of the vote . If only one candidate got over 20 % of the vote and not a majority , the delegates would be allocated between the candidate that got over 20 % of the vote and the candidate who received the 2nd most votes . If no candidate got 20 % , they would allocate all of the 47 at-large delegates proportionally
