With the Iowa caucuses a year away, a new poll finds a majority of Americans would “definitely not vote” to re-elect President Donald Trump, while most Democratic voters do not know who they want to nominate to challenge him.

According to a Washington Post-ABC News poll, 56 percent of Democratic voters and independents who lean Democratic did not give a name when asked who they would vote for if their primary were today. The pollsters did not give the people they interviewed a list of candidates.

Among the Democratic contenders whom the respondents did name, former Vice President Joe Biden led with 9 percent. California Sen. Kamala Harris was second at 8 percent, followed by Vermont Sen. Bernie Sanders (4 percent), former Texas Rep. Beto O’Rourke (3 percent), former first lady Michelle Obama (2 percent) and Massachusetts Sen. Elizabeth Warren (2 percent).
