Why the GOP Dominates the House—But Not the Senate
July 26, 2011
Since the Second World War, there have been three instances of a divided partisan Congress. The first was the six-year stretch from 1981 to 1987, when Republicans held the Senate but not the House. Then, following the April 2001 party defection of Republican Senator Jim Jeffords, for most of the 107th Congress Republicans ran the House but shared power with Senate Democrats. And now there is the 112th Congress, featuring a Republican House majority and a Democratic Senate majority.
