Assessment of the Districts Where Democrats Are Challengers

Force Multiplier shows the highest-probability Democratic pickup opportunities (“flips”) are the Republican-held districts where recent margins were narrow, the Democratic challenger is well-known, and the district demographics favor competitive outcomes.

​

Below is a ranking based on structural competitiveness (recent vote margins, district partisanship, and candidate strength).
