UVA politics professor Larry Sabato said the euphoria Democrats have felt from a beleaguered President Trump has turned into depression as "reality" has hit them.

"That euphoria is gone and it's replaced with reality," Sabato told CNN's Don Lemon in an interview Tuesday night.

SABATO: The bigger picture to me is that the 2018 Congressional elections are a year and a half away and a million things can happen that can change the picture.

For Democrats obviously, it's pretty depressing. That's the word I've seen on Twitter more than any other from Democrats about the result. I think if Democrats learn a lesson from this election, it's that the euphoria that they felt for the last several months as Donald Trump has fallen in the polls and they began to believe that this would be not easy but doable to take over the House of Representatives and eventually replace Donald Trump, that euphoria is gone and it's replaced with reality. And the reality is, it's going to be a long twilight struggle. Day in and day out if they're going to be able to retake the House and eventually defeat Donald Trump. iI won't be easy. It may not be possible but it certainly won't be easy.
