Why this exists

Give where it matters.

There are hundreds of races for Congress in 2026. Most donors give to the campaigns with the biggest names or the most emails. Those often aren't the races where your money or time changes the result.

Tip the Scale Blue ranks every Senate and House race by how much your help could change the outcome, so you can start with the races that need it most.

How the score works

Every race gets a score from 0 to 1000. Higher means more worth acting on. The score combines:

·How close the polls are. The biggest factor: a 2-point race scores far higher than a 12-point race.
·Expert ratings. The consensus of Cook Political Report, Sabato's Crystal Ball and Inside Elections.
·Fundraising. Races where the Republican has more cash than the Democrat score higher.
·Control of Congress. The fewer seats Democrats can afford to lose, the more each competitive race counts.
·Voting records. Progressive Punch scores for both candidates. Replacing a bad vote counts for a lot.
·Endorsements from progressive groups such as Emily's List, Working Families Party, Sunrise and Justice Democrats.
