2013 Report Cards
Senate Sophomores
These special year-end statistics dissect the legislative records of Members of Congress during the 2013 legislative year (Jan 3, 2013-Dec 26, 2013), looking at Members who served at the end of that period. This page was last updated on Dec 1, 2014.
A higher or lower number below doesn’t necessarily make a legislator any better or worse, or more or less effective, than other Members of Congress. We present these statistics for you to understand the quantitative aspects of legislating and make your own judgements based on what legislative activities you think are important.
Keep in mind that there are many important aspects of being a legislator besides what can be measured, such as constituent services and performing oversight of the executive branch, which aren’t reflected here.

Government Transparency

Ideology Score
Our unique ideology analysis assigns a score to Members of Congress according to their legislative behavior by whether they sponsor and cosponsor overlapping sets of bills and resolutions with other Members of Congress. The score can be interpreted as a left—right scale measuring the dominant ideological difference or differences among Members of Congress, although of course it only takes into account a small aspect of reality.

For more, see our methodology. Although we do not report a margin of error, the scores fluctuate significantly over time because of the limited data used in the analysis. 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.

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.

... EXPAND ... |
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.

Missed Votes
The percentage of votes each legislator missed in 2013.

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.

Companion bills are those that are identified as “identical” by Congress’s Congressional Research Service.
Writing 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 introduced by each legislator in 2013 which had both a Democratic cosponsor and a Republican cosponsor.

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.
