How party polarization makes the legislative process even slower when government is divided

Since 2010, the U.S. has experienced divided government, with the Democrats holding the White House, and The Republican Party controlling the House of Representatives, and since January, the Senate. In new research which analyses the passage of 2,200 bills from 1949 to 2010, Tyler Hughes and Deven Carlson find that divided government slows down the legislative process by 60 days, on average. This delay is made even worse when the level of party polarization is higher, which makes partisan compromises even more difficult.
