When will Senator Bernie Sanders drop out? That's been the question on the minds of nervous Democratic Americans since Hillary Clinton clinched enough delegates [1] to become the presumptive nominee for president. Today we got a hint of the answer. After meeting with President Barack Obama, Sanders said he'll continue to stay in the race through the final primary, which takes place in Washington DC on June 14, making that the likely day he'll concede.

The fact that he's not dropping out immediately does not mean Sanders wants to play spoiler to Hillary Clinton. He's been adamant about his desire to give every American a chance to cast their vote in the primary. The more votes he gets, even if he's already mathematically disqualified, is a vote for Sanders's principles [2]. And he can use that momentum to shape the party platform.

Following the meeting, Sanders made it clear that he will join Hillary Clinton's side in the general election. He said, "I spoke briefly to Secretary Clinton on Tuesday night and I congratulated her on her very strong campaign. I look forward to meeting with her in the near future to see how we can work together to defeat Donald Trump and create a government which represents all of us and not just the one percent." Earlier in the speech, he also turned his attention to Trump, saying:

Donald Trump would clearly, to my mind and I think the majority of Americans, be a disaster as president of the United States. It is unbelievable to me, and I say this with all sincerity, that the Republican party would have a candidate for president who in the year 2016 makes bigotry and discrimination the cornerstone of his campaign.

In my view, the American people will not vote for or tolerate a candidate who insults Mexicans and Latinos, who insults Muslims, who insults African Americans and women. Needless to say, I am going to do everything in my power and I will work as hard as I can to make sure that Donald Trump does not become president of the United States.

Sanders said he will bring his passion for solving poverty, student debt, and inequality to the Democratic National Convention in July. Watch his address above.
