An overwhelming majority of voters believe the president will return to the Oval Office after the next election, a new survey has found.

Monmouth University Polling Institute’s latest poll confirmed 66 percent of American voters think President Donald Trump will either definitely or probably be re-elected at the general election on Nov. 3. About a quarter of respondents (28 percent) thought the president would either definitely or probably lose to any Democratic presidential candidate.

“[President Trump’s] steady ratings through the entire impeachment process and memories of how 2016 turned out suggest that few are willing to bet against him,” Monmouth Director Patrick Murray said in a statement.

The results add weight to the argument that support for the president and Republican Party continues to grow despite months of impeachment investigations and multiple acts of defiance from Democrats.

The outcome of the Iowa caucus also did not change the minds of voters and delivered a major blow to support for former Vice President Joe Biden who previously attracted 30 percent.

“Iowa has had a significant impact on the race, especially for Biden, whose support was always soft and based largely on the perception of electability,” Murray said.

Sen. Bernie Sanders’s (I-Vt.) 26 percent ranked ahead of Biden’s new 16 percent, former South Bend Mayor Pete Buttigieg’s 13 percent, Sen. Elizabeth Warren’s (D-Mass.) 13 percent, former New York City Major Michael Bloomberg’s 11 percent, and Sen. Amy Klobuchar’s (D-Minn.) 6 percent. Andrew Yang had 4 percent and has since suspended his election campaign.

“Sanders is on the rise but his gains have come mainly in states that vote after Super Tuesday [so] there is still time for a number of candidates, including Sanders, to build or lose momentum,” Murray said. “The Democratic nomination kickoff in Iowa did not exactly inspire confidence in the party’s ability to find someone who can take on the president.”

Ninety-three percent of Republican voters said the party will either definitely or probably be re-elected while only 11 percent of Democratic supporters thought that party’s nominee would actually defeat the incumbent president. Only 44 percent of Democratic voters said Trump would probably lose the election.

Overall 65 percent of voters said they were optimistic about the 2020 presidential election compared to just 30 percent who were pessimistic. The most optimistic respondents supported the Republican Party (86 percent).

“Enthusiasm is up compared to 2016 but optimism has split along party lines,” Murray said. “These conflicting findings in public opinion seem to reflect the muddled state of the race on the Democratic side right now.”
