Based on most polls throughout 2019, former vice president Joe Biden, a moderate, keeps himself as a fragile front-runner on the sprawling field of Democratic challengers, followed by senators Bernie Sanders and Elizabeth Warren who are splitting the progressive vote.

To the surprise of many people, tech entrepreneur Andrew Yang has slightly overtaken Pete Buttigieg, mayor of South Bend in Indiana, in the 2020 Democratic primary net favorability rankings, according to a Morning Consult poll published on Tuesday. Former New York City mayor Michael Bloomberg, Minnesota Senator Amy Klobuchar, New Jersey Senator Cory Booker, activist Tom Steyer and House lawmaker Tulsi Gabbard from Hawaii are also fighting hard in hopes of becoming the party's banner-holder in the 2020 elections.

However, beyond topics over Trump, the candidates disagree a lot, as six primary debates held by the party's national committee this year have shown. The issues they argue range from Medicare for All, free college, gun control, wealth tax to climate change. Progressive agenda has garnered much more support among Democratic voters than before.

This raises great suspense: Who will win the party's 2020 presidential candidacy, a progressive, a moderate, or someone in between?

"Democratic Party voters are split," said Thomas Edsall with Columbia University, citing a CBS survey breaking Democratic voters into three roughly equal groups: the most progressive wing, the middle group pressing bread-and-butter concerns like jobs, taxes and moderate health care reform, and those Democratic primary voters who describe themselves as moderate to conservative.
