Al Franken’s short voting history thus far (12 recorded votes) is reasonably liberal, putting him just to the left of the Democratic median, in the neighborhood of Bernie Sanders, Daniel Inouye, and the two NY senators Schumer and Gillibrand. Franken’s underlying ideal point (as revealed by analysis of these 12 votes) places him unambiguously to the left of the other MN senator, Klobuchar.
