Trump won the state with 58.09% of the vote, while Clinton received 38.45%. Trump performed slightly better in the state than Mitt Romney in 2012, but also slightly worse than John McCain in 2008. In contrast, Clinton's vote share in the state was a decrease from Barack Obama's vote shares in 2012 and 2008, where he earned 40.58% and 39.93%, respectively. This makes it the largest loss by a Democrat since Democratic nominee Walter Mondale in 1984. Louisiana is also one of 11 states whose electoral votes went to Bill Clinton twice, but which Hillary Clinton did not win. Six of those states, including Louisiana, have not supported any Democratic Presidential candidate since Bill Clinton (The other five being Arkansas, West Virginia, Kentucky, Tennessee, and Missouri), while an additional five (Iowa, Ohio, Wisconsin, Michigan, and Pennsylvania) had all voted Democratic at least twice since Bill Clinton's re-election in 1996.
On March 24, the State Convention met in an attempt to reverse the results of the primary, giving Ted Cruz a clear majority.
After conflicting reporting of their support for Ted Cruz, four of Rubio's five delegates publicly rebuked the reporting and committed to staying undecided. Rubio's five delegates and 2 uncommitted delegates committed to Trump after Kasich and Cruz dropped out of the race. This gave Trump the majority of the delegates from the state.
Donald Trump won the election in Louisiana with 58.1% of the vote. Hillary Clinton received 38.4% of the vote. Of the 2,029,032 total votes cast, Trump had 1,178,638 while Clinton had 780,154 votes. All of Louisiana's parishes voted for the same party they voted for in 2012 and 2008. As a result, this marked the first time since 1992 that East Baton Rouge Parish backed the losing candidate of the election, and the first time since 1948 that East Baton Rouge Parish voted for the Democratic candidate three elections in a row; Trump also became the first Republican to win the White House without carrying this parish since Richard Nixon in 1968.
Louisiana was one of eleven states that voted twice for Bill Clinton in 1992 and 1996 which Hillary Clinton lost in 2016.
