A new Monmouth University Poll says Former Vice President Joe Biden is the front-runner among likely Democratic caucusgoers in Nevada.

Massachusetts Sen. Elizabeth Warren takes second place, and Vermont Sen. Bernie Sanders takes third. 

Out of 24 candidates currently running, Biden holds a lead with 36% support among registered Democrats. He is followed by Warren at 19% and Sanders at 13%.

The poll shows 12 candidates earned less than 1% or were not chosen by any respondents in the poll. 

"Nevada is the first state on the Democrats' 2020 calendar with an ethnically diverse electorate. Latino voters seem to be particularly up for grabs right now," says Patrick Murray, director of the independent Monmouth University Polling Institute. 

The poll also says that health care tops the list of concerns for Democratic voters, but it says that immigration is more of a factor for choosing a nominee in Nevada than it is in other early states. The environment, jobs, social security, gun control and reproductive rights are also concerns for voters. 

Nevada will hold its Democratic caucus on February 20, 2020. Republicans have yet to announce a date for their caucus. 

The poll was conducted by telephone June 6-11, 2019 with 370 Nevada voter who are likely to attend the caucus, out of 1,333 registered Democrats and unaffiliated voters. The margin of error is +/- 5.1 percentage points. 

On Wednesday, President Trump was asked about polling. He said, “We do very little polling because I'm not a huge believer in polling. I think you go out there and you fight and you don't really need polls, you need ideas more than polls. But we have some internal polling, very little, and it's unbelievably strong, the strongest I've ever been, is exactly today.”
