A nonpartisan group with a bipartisan board has again named U.S. Sen. Gary Peters its most effective U.S. senator

It is the second consecutive term that Mr. Peters (D-Bloomfield Township) has received the distinction from the Center for Effective Lawmaking.

The 117th rankings: The Center for Effective Lawmaking released a new report ranking how successful lawmakers were during the 117th Congress in advancing legislative measures.

Note: The scores have been divided by party, as lawmakers' average legislative effectiveness score can be determined by whether they stand within the majority or minority party. The data also provides a benchmark score to consider for the influence of party status, level of seniority, or chair position on a committee or subcommittee.

The methodology: The organization, which is backed by the University of Virginia and Vanderbilt University, was created in 2017 to promote "legislative effectiveness" among lawmakers across the U.S. Their report analyzes 15 factors to quantify how lawmakers advance their bills. Some of these factors include how many bills lawmakers sponsor, the number of bills that receive action in committee, and how many move beyond their original panel. More on their methodology.
