Weirdly enough, it was the latter, sort of.
After the first year of this 114th Congress, more bills have been enacted than in the 112th or 113th, according to data compiled by GovTrack.us. So far, the 114th is tracking more closely with the more-productive 110th and 111th.
Of course, on the scale of Congresses going back to the 1970s, the 114th Congress still trails. It had the sixth-least-productive first year of any Congress since the 93rd (which was one of the most productive).
Most legislation in a Congress is passed at the tail end of the two years, often in the weeks after the last election. (Weird, right?) So it's hard to say how productive this Congress will be overall.
In January, we pointed out that the 114th was off to a fast start, enacting its first legislation within a week of coming into session. This is not a blistering pace, but at least it's a pace.
Not that this will make everyone happy.
