Donald Trump won all five states at play in Tuesday's Republican presidential primary contests. On the Democratic side, Hillary Clinton won four out of the five states up for grabs.
Trump beat out his Republican rivals, U.S. Sen. Ted Cruz (R-TX) and Ohio Gov. John Kasich, by large margins in Connecticut, Delaware, Maryland, Pennsylvania, and Rhode Island.
Tuesday's election results bring the total delegate count thus far to 950 for Trump, 560 for Cruz and 153 for Kasich, according to the Associated Press' delegate tracker.
A total of 1,237 delegates is necessary to win the GOP presidential nomination.
"I consider myself the presumptive nominee. Absolutely," Trump stated Tuesday.
"As far as I'm concerned, it's over," he added.
In the Democratic presidential primary race, Clinton beat out Bernie Sanders in Connecticut, Delaware, Maryland and Pennsylvania. Sanders was victorious in Rhode Island.
A candidate must secure at least 2,383 delegates to clinch the Democratic nomination. Clinton currently has 2,141 total delegates, including super delegates, while Sanders comes in at 1,321.
"Now, with your help we're going to come back to Philadelphia for the Democratic National Convention with the most votes and the most pledged delegates," Clinton told supporters at a rally in Philadelphia. "We will unify our party to win this election and build an America where we can all rise together, an America where we lift each other up instead of tearing each other down."
Speaking Tuesday evening at a rally in West Virginia, which will hold its primary on May 10, Sanders stressed that he has no interest in bowing out of the race. In a statement issued after the rally, Sanders reiterated that he is "in this race until the last vote is cast," adding that he "look[s] forward to issue-oriented campaigns in the 14 contests to come."
The statement suggested that Sanders may be changing his focus from winning the Democratic nomination to shaping the party platform at the Democratic National Convention.
"That is why this campaign is going to the Democratic National Convention in Philadelphia with as many delegates as possible to fight for a progressive party platform that calls for a $15 an hour minimum wage, an end to our disastrous trade policies, a Medicare-for-all health care system, breaking up Wall Street financial institutions, ending fracking in our country, making public colleges and universities tuition free and passing a carbon tax so we can effectively address the planetary crisis of climate change," Sanders said.
