Election analyst says any Republican that challenges Trump in 2020 won't be 'politically serious'

Polling and election analyst Henry Olsen on Wednesday said that if President TrumpDonald John TrumpTrump passes Pence a dangerous buck Overnight Health Care — Presented by American Health Care Association — Trump taps Pence to lead coronavirus response | Trump accuses Pelosi of trying to create panic | CDC confirms case of 'unknown' origin | Schumer wants .5 billion in emergency funds Trump nods at reputation as germaphobe during coronavirus briefing: 'I try to bail out as much as possible' after sneezes MORE faces a primary challenge in 2020, it will most likely be by a candidate who is not politically serious. 

"The faction of dissident Republicans is not large enough to win a primary, much less a general election," Olsen told Hill.TV's Joe Concha on "What America's Thinking." 

"I think Trump will be primaried, but I don't think that it'll be by anyone terribly politically serious," he continued. "It is like George H.W. Bush was primaried by Pat Buchanan in 1992 because nobody with a political future was willing to be a sacrificial lamb."

"I'm expecting somebody like a Bill Kristol or [Charlie Sykes] or one of his 'Never Trump' media critics to go up and play the Pat Buchanan role this time," Olsen said. 

While Ohio Gov. John Kasich (R) has been floated as a potential Republican challenger to Trump, the president still enjoys high approval ratings among his Republican base. 

Eighty-nine percent of Republicans said last week that they approved of Trump's job as president, according to Gallup.
