The 104th Congress of 1995-1996 under Speaker Newt Gingrich and Senate Majority Leader Bob Dole had the worst performance of any Congress in fifty years, when it passed only 333 bills into law.
But now the 112th Congress has surpassed the 104th Congress in mediocrity, as under Speaker of the House John Boehner and Senate Majority Leader Harry Reid, ONLY 219 bills have been passed, and this coming after the 111th Congress (2009-2010) was the most productive since the 89th Congress (1965-1966) under President Lyndon B. Johnson!
The common thread of the 112th and the 104th Congresses is that in both cases, the House of Representatives was under Republican control, and with Republican control also in the US Senate for the 104th Congress. Split party control in the past two years between Democrats and Republicans turned out worse than the Republican control of both houses in 1995-1996!
