Former Secretary of State Hillary Clinton is leading the Democratic contest in Ohio by 21 percentage points, according to a poll released Monday by the Democratic-leaning firm Public Policy Polling.

The poll showed Clinton at 56 percent support, easily beating out Sen. Bernie Sanders (I-VT), who stood at 35 percent.

There has been very little polling of Ohio voters, but these results are consistent with the few other polls, which show Clinton with a substantial lead. There is not enough data to generate a TPM PollTracker Average.

The PPP poll was conducted from March 4-6. Pollsters surveyed 508 people likely to vote in the Democratic primary, with a margin of error of 4.4 percentage points.
