FACT CHECK: Harris has liberal voting record, but Pence's claim she's 'most liberal' leaves out context
PENCE'S CLAIM: "It's probably why Newsweek magazine said that Kamala Harris was the most liberal member of the United States Senate in 2019, more liberal than Bernie Sanders, more liberal than any of the others in the United States Senate."
FACT CHECK: Harris certainly has a very liberal Senate voting record, and an analysis cited by Newsweek in 2019 did find her to be the most liberal in the U.S. Senate.
However, that particular analysis does not consider some important caveats, the founder of the organization who conducted it told ABC News.
Harris certainly has one of the more liberal voting records in the Senate: She has voted to increase gun control and block conservative judicial nominees, for instance.
But there are nuances that the organization's founder, Jonathan Tauberer, said GovTrack's model doesn't account for, like the complexity of Harris' political views, the distinctions between different wings within each major political party, the specific approach Harris might take to achieve her desired outcome, or the unwillingness of Republicans to work with Harris during a presidential year.
