Government Transparency

GovTrack looked at whether legislators supported any of the government transparency, accountability, and effectiveness bills that we identified in 2013. We gave a score to each legislator based on one point for cosponsoring and three points for sponsoring any of these bills.

Ideology Score

Our unique ideology analysis assigns a score to Members of Congress according to their legislative behavior by how similar the pattern of bills and resolutions they cosponsor are to other Members of Congress. The score can be interpreted as a conservative—liberal scale, although of course it only takes into account a small aspect of reality.

Senate Freshmen
most conservative
#1 0.86 Sen. Deb Fischer [R-NE]
#2 0.85 Sen. Tim Scott [R-SC]
... EXPAND ...
#14 0.09 Sen. Edward “Ed” Markey [D-MA]
#15 0.03 Sen. Elizabeth Warren [D-MA]
most liberal

For more, see our methodology. An ideology score is not computed for Members of Congress who introduced fewer than 10 bills or who have a low leadership score, as there is usually not enough data in these cases to compute reliable statistics. Note that because on this page only legislative activity in 2013 is considered, the ideology score here may differ from those elsewhere on GovTrack.

 

Joining Bipartisan Bills

In this era of partisanship, it is encouraging to see Members of Congress working across the aisle. This is the percent of bills cosponsored by each legislator which were introduced by a member of the other party.

Senate Freshmen
most often
#1 38.6% Sen. Heidi Heitkamp [D-ND]
#2 30.5% Sen. Joe Donnelly [D-IN]
... EXPAND ...
#12 14.9% Sen. Mazie Hirono [D-HI]
#13 11.4% Sen. Elizabeth Warren [D-MA]
least often

Only Democratic and Republican Members of Congress who cosponsored more than 10 bills and resolutions are included in this statistic.

 

Laws Enacted

The number of bills each legislator introduced that became law in 2013. Keep in mind that it takes a law to repeal a law. Very few bills ever become law.

We only count enacted bills (and joint resolutions) that the legislator was the primary sponsor of. While a legislator may lay claim to authoring other bills that became law, such as through companion bills or incorporation into larger bills, these cases are difficult for us to track quantitatively.

 

Leadership Score

Our unique leadership analysis looks at who is cosponsoring whose bills. A higher score shows a greater ability to get cosponsors on bills.

Senate Freshmen
top leader
#1 0.82 Sen. Elizabeth Warren [D-MA]
#2 0.64 Sen. Angus King [I-ME]

#14 0.01 Sen. Cory Booker [D-NJ]
#15 0.00 Sen. Tim Scott [R-SC]
bottom follower

For more, see our methodology. A leadership score is not computed for Members of Congress who introduced fewer than 10 bills, as there is usually not enough data in these cases to compute reliable statistics. Note that because on this page only legislative activity in 2013 is considered, the leadership scores here may differ from those elsewhere on GovTrack.

 

Missed Votes

The percentage of votes each legislator missed in 2013.

Senate Freshmen
most absent
#1 6.9% Sen. Jeff Flake [R-AZ]
#2 5.5% Sen. Ted Cruz [R-TX]
... EXPAND ...
#13 0.0% Sen. Deb Fischer [R-NE]
#13 0.0% Sen. Joe Donnelly [D-IN]
#13 0.0% Sen. Tammy Baldwin [D-WI]
most present

The Speaker of the House is not included in this statistic because according to current House rules, the Speaker of the House is not required to vote in “ordinary legislative proceedings, and the delegates from the five island territories and the District of Columbia are also not included because they were not elligible to vote in any roll call votes.

 

Powerful Cosponsors

The number of bills that each legislator introduced in 2013 that had a cosponsor who was a chair or ranking member of a committee that the bill was referred to. Getting support from committee leaders on relevant committees is a crucial step in moving legislation forward.

Senate Freshmen
most often
#1 10 Sen. Edward “Ed” Markey [D-MA]
#2 2 Sen. Jeff Flake [R-AZ]
... EXPAND ...
 

Working with the Other Chamber

The House and Senate often work on the same issue simultaneously by introducing companion bills in each chamber. This is the number of bills introduced by each legislator in 2013 that had a companion bill in the other chamber. Working with a sponsor in the other chamber makes a bill more likely to be passed by both the House and Senate.

Senate Freshmen
most bills
#1 5 Sen. Christopher Murphy [D-CT]
#1 5 Sen. Mazie Hirono [D-HI]

Companion bills are those that are identified as “identical” by Congress’s Congressional Research Service.

Additional Notes

The Speaker’s Votes: Missed votes are not computed for the Speaker of the House. According to current House rules, the Speaker of the House is not required to vote in “ordinary legislative proceedings.” In practice this means the Speaker of the House rarely votes but is not considered absent.

Leadership/Ideology: The leadership and ideology scores are not displayed for Members of Congress who introduced fewer than 10 bills, or, for ideology, for Members of Congress that have a low leadership score, as there is usually not enough data in these cases to compute reliable leadership and ideology statistics.

Missing Bills: We exclude bills from some statistics where the sponsor’s original intent is not in the final bill because the bill’s text was replaced in whole with unrelated provisions (i.e. it became a vehicle for passage of unrelated provisions).

Ranking Members (RkMembs): The chair of a committee is always selected from the political party that holds the most seats in the chamber, called the “majority party”. The “ranking member” (sometimes “RkMembs”) is the title given to the senior-most member of the committee not in the majority party.

Freshmen/Sophomores: Freshmen and sophomores are Members of Congress whose first term (in the same chamber at the end of 2013) was the 113th Congress (freshmen) or 112th (sophomores). Members of Congress who took office within the last few months of a Congress are considered freshmen in the next Congress as well.
