Election results by county.
Mississippi's 40 Republican delegates were contested. Donald Trump won the primary, receiving 47.24% of the vote, while Ted Cruz came in second, with 36.12% of the vote. Trump received 25 of the state's delegates, while Cruz received the remaining 15.
Trump had already become the Republican front-runner before the Mississippi primary. He was favored to win Mississippi partly because he had already done well in Southern states' primaries, including Alabama's, which he won with 43.4% of the vote on Super Tuesday.

Trump's double-digit victory in Mississippi was seen as solidifying his status as the Republican front-runner, shortly after his disappointing performance in the Louisiana primary. Another unusual aspect of the Mississippi primary results was Marco Rubio's exceptionally poor showing: Rubio came in fourth despite having finished second in several other primaries in the South. Overall, Trump's victory was part of his generally strong performance in the South, in which, as a whole, he performed better than either John McCain in 2008 or Mitt Romney in 2012.
Exit polls showed that Trump beat Cruz in virtually every demographic group. They also showed that Trump got an especially large share of the vote among Mississippi voters looking for a candidate who "tells it like it is". Trump also won among white evangelicals, the voters who Cruz had hoped would form his coalition. However, Trump came in second (behind Cruz) among Republican voters who decided whom to vote for in the primary within the previous week.
