The survey finds Biden mopping up among older people and working-class voters.

Biden has support from 44 percent of those respondents over the age of 65. He has Thirty-eight percent of those surveyed who are earning less than $50,000 per year support him, as do 34 percent of respondents without a college degree.

“If Biden does get into this race, he’ll start out as a clear front-runner in Iowa," said Patrick Murray, the director of the Monmouth University Polling Institute. "Not only does he garner support from crucial demographic groups but he is almost universally well-liked among all Democratic voters.”

Biden is expected to launch his presidential campaign sometime after Easter.

The controversy that exploded after several women accused him of inappropriate touching at public events does not appear to have tarnished his image among Democratic voters.

Seventy-eight percent of Iowa Democrats have a favorable view of Biden, compared to only 14 percent who view him unfavorably. That’s the best net favorability rating in the field.

Sanders is at 67 percent favorable and 26 percent unfavorable. Buttigieg posts a 45 percent to 9 percent favorable-unfavorable split.

“Buttigieg’s current standing in the horse race is impressive given that nearly half of likely Democratic caucus-goers have yet to form an opinion of him," Murray said. "He has one of the best positive to negative ratios in the field. He could move up if he is able to maintain that rating as he introduces himself to more voters. Klobuchar is another candidate with potential to increase her support as she becomes better known, based on her current ratings ratio."

At 51 percent, health care is far and away the top issue for Iowa Democrats, with climate change a distant second at 17 percent.

“Here’s one example of why this race is very open despite the possibility of having a nominal front-runner if Biden gets in," Murray said. "Health care and the environment are clearly the top issues in this race, but it doesn’t look like any candidate owns a clear advantage on them. And there are a bunch of other issues that candidates may be able to leverage into voter support over the next few months.”

The Monmouth University survey of 351 likely Democratic caucus-goers in Iowa was conducted between April 4 and April 9 and has a 5.2 percentage point margin of error.
