"One of the risks for Democrats in 2020— specially at the presidential level—is that the impeachment process will suck up all the oxygen that otherwise might have been available to make the affirmative case for election," says Professor of Political Science Grant Reeher.

"It’s damning by any account just for the mere fact that he asked a foreign leader to investigate private citizens for potential personal political gain is egregious," says Christopher Faricy, associate professor of political science. "The question, what else is out there that we are not aware of, either with the Ukranian President or even other countries and leaders."

"The more moderate Democrats are recalculating, thinking they have to get on board with this [President Trump's impeachment] or face primaries" from left-leaning insurgents, says Professor of Political Science Grant Reeher. "The facts have also changed" since the Russia investigation, he adds.
