The Center for Effective Lawmaking (CEL) recently published a study of legislative effectiveness in the 116th U.S. Congress, which ran from Jan. 3, 2019, to Jan. 3, 2021.
"We've found initial patterns that those more effective tend to be what we would call the workhorses rather than the show horses, and because of their policy focus, they're less likely to be called upon by the media," said Craig Volden, co-director of the CEL.
"We've kind of relatedly found that those who are called on by the media, that there tends to be more of an interest in talking about ... politicking and personalities than there is in talking about policy and lawmaking."
Sens. Marco Rubio (R-FL) and Gary Peters (D-MI) were ranked most effective Senators in their respective parties. Reps. Michael McCaul (R-TX) and Nita Lowey (D-NY) were the most effective of their respective parties in the House.
Rep. Alexandria Ocasio-Cortez (D-NY) and House Speaker Nancy Pelosi (D-CA) are ranked No. 230 and 237, respectively, in legislative effectiveness out of 240 Democrats in the 116th U.S. Congress. Rep. Jim Cooper (D-TN) came in the last place for the Democrats.
"The scores are based on the combination of fifteen metrics regarding bills that each member of Congress sponsors, how far they move through the lawmaking process, and how substantial their policy proposals are," Volden said. "More on our methodology can be found here."
