"It's been a tough week," said Bernie Sanders in his post-election interview with Stephen Colbert [1] on The Late Show Monday. The thoughtful and reflective interview touched on the election's outcome, grassroots movements, and his new book Our Revolution.

At the start of the discussion, Colbert questioned Sanders about the way in which Donald Trump [2] appealed to the working class, a faction that Sanders also appeals to but in a different way. On the main difference between their campaigns, Sanders said, "Above and beyond, the incredible bigotry of the Trump campaign." He did note that Trump "tapped into a lot of pain and anxiety and angst that American people are feeling . . . At the end of the campaign, Trump was posing as a hero of the working class of America. Now, I happen not to believe him. I hope I'm wrong."

Sanders — the former Democratic candidate who has a well-documented involvement in the civil rights movements — said it's now important for Trump's critics to assert themselves [3] following the election. "Let's be clear about this election: Hillary Clinton ended up with two million more votes than Donald Trump. So, don't see this as a massive success for Trump," he said. "Our job now, in my view, is to figure out how we create an effective opposition."

In another clip, shown below, Sanders spoke about the "liberal elite" and the perception of the Democratic party as being out of touch with the average American. As a result, Sanders urged the party to "feel the pain of working class people" and thereby become more inclusive.

Despite Trump's win, however, Sanders said he has not lost hope. "The vast majority of the American people are on our side. Trump's views are a minority . . . What you do now is get involved heavily in the political process. When millions of people stand up and fight back, we will not be denied."
