Former White House communications director Anthony Scaramucci sees a landslide re-election for President Donald Trump in 2020, saying on Wednesday that voters will be wary of meddling with the success of Trump's economic policies.

Making a wild prediction on CNBC's "Squawk Box," Scaramucci said, "I think he'll get resoundingly re-elected. He'll probably have a 40 state landslide, because what are you going to do? You're going to put a socialist in place and wreck the entire economy?"

No candidate has won 40 states in a general election since George H.W. Bush in 1988. Ronald Reagan carried 49 states in his 1984 reelection bid, and Richard Nixon won by the same margin in 1972. Trump lost the popular vote in the 2016 election, but won 28 states and 306 electoral votes, making him the country's 45th president.

The president would prefer to face the more moderate former Vice President Joe Biden in the 2020 general election, said Scaramucci, the founder of the SkyBridge Capital hedge fund who famously served in the Trump White House as communications director for less than two weeks in 2017. "I think he wants Biden because I think he can compare and contrast himself to the 50-year establishment failure in Washington."
