Only 36% of Americans can name the three branches of government

That’s according to a new survey from the Annenberg Public Policy Center, and it shows a huge percentage of Americans might need to take a civics refresher course.

Only 38 percent of Americans knew the Republican Party controls the U.S. House of Representatives, while 17 percent think Democrats are still in charge. The number of people who knew Republicans were in charge has dropped 17 percent since the last time Annenberg asked, back in 2011, right after Republicans reclaimed control.

An identical number, 38 percent, knows Democrats run the Senate, while 20 percent believe Republicans control the upper chamber. Only 27 percent knew it takes a two-thirds majority of the House and Senate to override a presidential veto.
