The fourth round of Democratic debates will be held on Oct. 15 — and possibly Oct. 16 — near Columbus, Ohio, with at least 11 candidates onstage.

How it works: This debate has the same requirements as September's. Qualifying candidates must reach 2% in 4 DNC-approved polls and draw 130,000 unique donors — including 400 donors in 20 different states. Oct. 1 is the final day to make the cut.

The DNC research team has mined thousands of lawsuits from nearly 50 states as part of a massive new trove on President Trump that will be weaponized through pols and reporters in key battlegrounds.

Why it matters: This new plan shows what Democrats think Trump's biggest vulnerabilities will be. And unlike in 2016, Trump now has a policy record.
