Does 28 not sound like a lot? Very few bills are ever enacted — most legislators sponsor only a handful that are signed into law. But there are other legislative activities that we don’t track that are also important, including offering amendments, committee work and oversight of the other branches, and constituent services.

We consider a bill enacted if one of the following is true: a) it is enacted itself, b) it has a companion bill in the other chamber (as identified by Congress) which was enacted, or c) if at least about half of its provisions were incorporated into bills that were enacted (as determined by an automated text analysis, applicable beginning with bills in the 110th Congress).

Missed Votes

From Jan 1989 to Jan 2013, Lieberman missed 485 of 7,907 roll call votes, which is 6.1%. This is much worse than the median of 2.0% among the lifetime records of senators serving in Jan 2013. The chart below reports missed votes over time.

We don’t track why legislators miss votes, but it’s often due to medical absenses, major life events, and running for higher office.
