The two current front-runners for the Democratic nomination, former Vice President Joe Biden and U.S. Sen. Elizabeth Warren, both beat the president by double digits among Minnesota voters. Voters polled picked Biden over Trump by 12 percentage points, 50% to 38%.

Warren, who attracted a large crowd at an August campaign rally in St. Paul, tops Trump 51% to 40%. U.S. Sen. Bernie Sanders, who places third in most national polls of the Democratic field, is ahead of Trump 49% to 40%.

The survey also asked voters about a hypothetical match-up between Trump and Minnesota’s Klobuchar, who trails in the crowded Democratic field. The third-term senator finished ahead of Trump by the widest margin, 55% to 38%. The poll of 800 registered voters, conducted Oct. 14-16, has a margin of error of 3.5 percentage points.

The poll was conducted less than a week after Trump visited Minneapolis for a high-profile campaign rally as part of an emerging effort by a Republican nominee to carry Minnesota for the first time since 1972. Trump vowed an all-out fight to win the state, which he narrowly lost to Democratic nominee Hillary Clinton in 2016.
