The last Super Tuesday of the primary season has ended with some significant steps for both parties.
On the Democratic side, Hillary Clinton officially declared herself the presumptive Democratic presidential nominee after winning four of the six states holding contests.
Clinton came away with a total of 372 delegates Tuesday and won California, New Jersey, New Mexico, and South Dakota.
Bernie Sanders received 283 delegates after winning the Montana primary and the North Dakota caucuses.
After the night's contests, Clinton has 2,755 delegates total, and Sanders has 1,852 delegates. These numbers include both pledged and superdelegates.
California was a very important state to win, as it holds the most delegates available for both parties. Four hundred and seventy five delegates were up for grabs for the Democrats.
To Clinton's benefit, California followed the pattern observed throughout the primaries, where she performed well in densely populated, delegate-rich urban areas like Los Angeles and San Francisco, while Sanders won rural parts of the state, including counties near the Oregon and Nevada borders, according to the Los Angeles Times.
By the end of the night, Clinton became the first woman to be the presumptive nominee for a major party, and Sanders announced that his campaign will continue, despite his defeat in California, a state where he focused considerable time and resources.
In the speech Sanders delivered following a victorious night for Clinton, Sanders acknowledged that the delegate math is not in his favor, but he announced that he plans to campaign for next week's Washington, D.C. primary and work toward the Democratic National Convention that will take place in Philadelphia on July 25.
Despite his promise to continue onward to the convention, some still speculate that a loss in D.C. might still result in the suspension of Sanders' campaign.
"I think sometime after D.C., and you've got to give him space, and room and respect, but I think he will probably get out," said Robert Shrum, the Carmen H. and Louis Warschaw Chair in Practical Politics at USC.
If Sanders decides to suspend his campaign after D.C., he will still likely have a strong influence at the convention, Shrum said.
"I think part of the decision to suspend his campaign would be an understanding with the Clinton campaign on some of these issues, and I think he will have a major role at the convention. He will speak. I think that he will have an influence on the platform," Shrum added.
On the Republican side, Donald Trump won in all of the states holding elections, as expected.
Trump finished the night with 1,536 delegates, when only 1,237 total delegates were needed to clinch the nomination.
Trump may have done well in the primaries, but he is now facing criticism that his campaign is too small and underdeveloped to succeed in the general election.
"You can't run a presidential campaign or a country with a little group or people and the principal deciding everything. You're going to make terrible mistakes," Shrum said, referring to the implications that the structure of Trump's current campaign could cause.
Despite these potential weak spots in his campaign, it appears the majority of the Republican Party will be willing to unite behind Trump come the general election if he is able to practice "good behavior," according to Shrum.
