Does 2 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).

Voting Record

Missed Votes

From Jan 1973 to Jul 1986, O’Brien missed 1,058 of 7,535 roll call votes, which is 14.0%. This is much worse than the median of 6.2% among the lifetime records of representatives serving in Jul 1986. The chart below reports missed votes over time.

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