Sen. Kamala Harris, Joe Biden’s newly picked running mate, was rated the “most liberal” U.S. senator in 2019, beating out Sen. Bernie Sanders, a Democratic Socialist, and Sen. Elizabeth Warren (D-Massachusettstan).
The rating was compiled by GovTrack, an organization that tracks U.S. lawmakers’ voting records and touts itself as “one of the oldest government transparency websites in the world.”
“Our unique ideology analysis assigns a score to Members of Congress according to their legislative behavior by how similar the pattern of bills and resolutions they cosponsor are to other Members of Congress,” the group says on its website. “The score can be interpreted as a conservative — liberal scale, although of course it only takes into account a small aspect of reality.”
