Does 90 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).
Grassley sponsors bills primarily in these issue areas:
Some of Grassley’s most recently sponsored bills include...
- S. 587: A bill to amend the Inspector General Act of 1978 to provide that ...

As President Pro Tempore of the Senate, Grassley may be focused on his responsibilities other than introducing legislation, such as setting the chamber’s agenda, uniting his party, and brokering deals.
From Jan 1981 to Mar 2021, Grassley missed 46 of 13,625 roll call votes, which is 0.3%. This is better than the median of 1.5% among the lifetime records of senators currently serving. 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.
