Chris Murphy’s allegiances are torn between the Red Sox and Big Blue — aka the New York Giants.

But there’s no ambiguity on which color in the political spectrum most defines the youngest and least-bankrolled member of the U.S. Senate.

Whether it’s threatening to go all Richard Sherman on Republicans over the unemployment benefits impasse or bemoaning the pay gap between hedge fund managers and teachers, Murphy tied for first in a recent National Journal ranking of the most liberal senators.

Murphy, 40, a freshman who took over the seat of estranged Democrat Joe Lieberman in 2013 and has been a central figure in the push for gun control reform since the Sandy Hook Elementary School shooting, shared the distinction with New York’s Chuck Schumer and Hawaii’s Brian Schatz.

Richard Blumenthal, the activist attorney general-turned-senior senator from Connecticut, was fifth.
