Who are the most vulnerable (from the left) among Democratic incumbents running for US House and Senate seats in 2026?

r/

The DCCC considers Democratic incumbents representing primarily the following types of districts, primarily, as vulnerable in 2026 general elections:

  1. Incuments in districts where Trump won the majority of district votes.

  2. Incumbents in districts that are heavy-Latino. (e.g. entire Nevada delegation)

The 26 Frontline members are: 

Josh Harder of California

Adam Gray of California

George Whitesides of California

Derek Tran of California

Dave Min of California

Jahana Hayes of Connecticut

Frank J. Mrvan of Indiana

Jared Golden of Maine

Kristen McDonald Rivet of Michigan

Don Davis of North Carolina

Nellie Pou of New Jersey

Gabe Vasquez of New Mexico

Dina Titus of Nevada

Susie Lee of Nevada

Steven Horsford of Nevada

Tom Suozzi of New York

Laura Gillen of New York

Josh Riley of New York

John W. Mannion of New York

Marcy Kaptur of Ohio

Emilia Sykes of Ohio

Janelle Bynum of Oregon

Henry Cuellar of Texas

Vicente Gonzalez of Texas

Eugene Vindman of Virginia

Marie Gluesenkamp Pérez of Washington

*I’d pobably add Jon Ossoff (Georgia) on the Senate side.

Which incumbents are the most vulnerable in 2026 Democratic primaries?

And are any incumbents listed above who are also at risk of being ousted by pimary challengers?
