"I think the best way to think about Trump and his movement is they're a moment, and this moment shall pass," Teixeira told Hill.TV's Jamal Simmons on Wednesday. "They're not going to be able to remake the country in their image. They're not going to be able to solve people's problems."

"We already see the backlash against that forming," he added. "We saw it in 2018. We may see it in 2020, where even though an incumbent president should get reelected, there's a very good chance that Donald Trump will not, and that a re-energized Democratic Party will take over the country in a more thorough way in the 2020 [contest]."

Teixeira was discussing his book, "The Optimistic Leftist," which encourages progressives to take a positive view on the future of 21st century America despite Trump's presidency.

"If you believe that you've got the best ideas and that you know how to deal with the current stage of our economy, the current stage of society and the current stage of the world, and your opponents, in fact, have bad ideas that won't work, well then, OK, be optimistic," he said.
