Political historian: 'I don't believe that you should base impeachment upon politics'

Political historian Allan Lichtman said on Thursday that even though Democrats have grounds to begin an impeachment inquiry against President TrumpDonald John TrumpNearly 300 former national security officials sign Biden endorsement letter DC correspondent on the death of Michael Reinoehl: 'The folks I know in law enforcement are extremely angry about it' Late night hosts targeted Trump over Biden 97 percent of the time in September: study MORE, he argued that it shouldn't be a political decision. 

“I don’t believe that you should base impeachment upon politics,” Lichtman, an American University professor who has correctly predicted the outcome of the previous nine presidential elections, told Hill.TV. 

“But in this case, there is no rift between doing what is constitutionally and morally right and what is politically right,” he added. 

Lichtman said the division among Democrats over whether to pursue an impeachment inquiry against Trump shows they are struggling over doing what is right and what is “politically expedient."

“Impeachment now is now on everyone’s lips, although I would say some like [Speaker] Nancy PelosiNancy PelosiGOP blocks Schumer effort to adjourn Senate until after election GOP noncommittal about vote on potential Trump-Pelosi coronavirus deal Overnight Health Care: Trump takes criticism of Fauci to a new level | GOP Health Committee chairman defends Fauci | Birx confronted Pence about Atlas MORE [D-Calif.] would like us to zip our lips about impeachment,” he said. “Democrats seem to be struggling between doing what is right and doing what is politically expedient.”
