Trump barely topped Texas Sen. Ted Cruz, who received 38 percent of the vote, while Florida Sen. Marco Rubio trailed with 11 percent and Ohio Gov. John Kasich received 6 percent. Trump held a rally in New Orleans East the night before the election, which was notable for dozens of protesters being thrown out (pictured), while Cruz held a more sedate event the same evening in Mandeville.
On the Democratic side, former Secretary of State Hillary Clinton notched an easy win over Vermont Sen. Bernie Sanders. Clinton received 71 percent of the vote to Sanders' 23 percent.
Both parties will hold their nominating conventions in July. The 2016 U.S. presidential election is Nov. 8.
