In 1993, Bill Clinton swept into office with a Democratic majority in both the House and Senate. His attempt to pass a controversial health-care bill failed but generated enough of a backlash that the Republicans took over both houses of Congress in 1995.
In 2001, George H.W. Bush entered the White House with Republicans in control of both houses. The events of 9/11 muted criticism of Bush for a time, but by 2007 Democrats had taken over Congress.
In 2009, Barack Obama became president and Democrats held both houses of Congress. He succeeded where Clinton failed in passing a health-care bill, but Republicans took over the House in 2011 and the senate in 2015.
