Below we use Weekly Common Space DW-NOMINATE scores to plot the Senate’s 62-37 vote to pass fast track trade authority for the president.

Senate Republicans split 48-5 in favor of the bill while Senate Democrats voted 14-32 against passage. The Senate Republicans who voted Nay are very ideologically dispersed (the most moderate and conservative Republicans—Senators Susan Collins [R-ME] and Mike Lee [R-UT]—both voted against passage), while the vote more clearly divides Senate Democrats on ideological lines, with Yea votes more likely to come from moderate Democrats such as Senators Heidi Heitkamp [D-ND] and Bill Nelson [D-FL]).
