Another 13 percent of Missouri’s Democrats remain undecided between Sanders and the Democratic presidential front-runner, it found.

Trump, meanwhile, leads the Republican field by 7 points in the Show Me State, according to Friday’s poll.

The Docking Institute conducted its latest sampling of 483 Missourians March 3–10. It has a 7 percentage point margin of error for Republicans and an 8-point margin of error for Democrats.

Friday’s results show both contests are up for grabs, as both show candidates within the margins of error.

Missouri awards 52 GOP delegates proportionally unless a candidate gets more than 50 percent of votes statewide. Should that happen, it is winner-take-all.

Democrats, meanwhile, pick 71 out of 84 Missouri delegates on March 15. The remaining 13 are superdelegates, most of whom are backing Clinton.

Missouri is one of five states voting that day, with Florida, Illinois, North Carolina and Ohio also casting ballots.

Trump leads the Republican field by more than 14 points nationwide, according to the latest RealClearPolitics average of polls. Clinton, meanwhile, holds a roughly 11-point edge over Sanders in the Democratic nomination contest.
