In spite of his record low approval ratings and a series of polls that peg him as the loser in the next presidential race, President Donald Trump reportedly believes that Sen. Bernie Sanders (I-Vt.)—who is seen as a top challenger to Trump in 2020 and currently the most popular politician in the country—is not “a serious threat and would be easy to beat.”

Politico reported late Monday that Trump had recently shared this view with “a Republican with close ties to the White House.” The 71-year-old president’s conclusion wasn’t based on politics; according to the anonymous Republican, “Trump was hung up on Sanders’ age, arguing that Sanders, now 76, wouldn’t have the energy to run another national campaign.”

Trump also brushed off a potential challenge from Sen. Elizabeth Warren (D-Mass.), a frequent target of the president’s public attacks. “He’s always asking people, ‘Who do you think is going to run against me?'” the Politico source said of Trump. “I don’t think he sees anyone, right now, being a serious competitor.”

The report comes as Trump’s approval rating remains below 40 percent, according to Gallup.
