A great deal of the Democratic party is unified in its disapproval of President Donald Trump — along with the majority of the American public. But a Harvard-Harris Poll provided exclusively to the Hill Tuesday indicated Democrats are an army without a chief: The party has been unable to find a new contender to rally behind during the 2020 presidential election.

Nearly 40 percent of registered Democrats say the party lacks a leader while 15 percent say former President Barack Obama is still the face of Democrats in Trump’s America, according to Tuesday’s poll. Vermont Sen. Bernie Sanders trailed the president, with 12 percent saying he's the leader of the party, followed by Sen. Elizabeth Warren with 11 percent. Meanwhile, the former Democratic presidential candidate Hillary Clinton received 10 percent of support from those surveyed.

Instead of flocking to rising Democratic voices like Rep. Joseph P. Kennedy III, D-Mass., many voters continued encouraging Trump’s former opponents in the 2016 election to bid for the top of the party’s ticket in 2020.

Sanders led the pack of potential candidates with just 14 percent of total support to become the Democratic candidate in 2020, followed by former first lady Michelle Obama. The party appeared to be divided over who should run against Trump four years from now, with several rumored candidates receiving fractions of support, including Clinton, media mogul Oprah Winfrey, New Jersey Sen. Corey Booker, Dallas Mavericks owner Mark Cuban and New York Gov. Andrew Cuomo.

It remained unclear if any of those named in Tuesday’s survey would even consider running against Trump, who bested Clinton in the Electoral College in last year's election.

While Obama repeatedly said she’d stay out political office after her husband’s Oval Office tenure, Winfrey hinted she was mulling a potential 2020 bid after witnessing Trump’s victory. Neither woman has served in elected office, but neither had Trump.
