Analyst says tensions among Dems will emerge after Trump leaves office

"What we saw in 2018, however, is that the great unifier for the Democratic Party is Donald Trump," Kamarch, a senior fellow at the Brookings Institution, told host Jamal Simmons on "What America's Thinking."

"So a lot of the tensions, I believe, are going to stay a little bit below the surface, until Trump's gone," she added.

"If Democrats manage to win the trifecta in 2020, then I think you're going to see a lot of these tensions come out: 'What do we do now? How do we do it?'" she said, referring to taking back control of the White House and Senate and maintaining power in the House. "But right now, I think Donald Trump is going to hold a lot of people together."

Democrats in 2018 won back the House after eight years of Republican control, but divisions in the caucus soon emerged between freshmen progressives and veteran lawmakers.
