There is virtually no difference between Republicans and Democrats on the question. Equal shares of both parties (38 percent) correctly identified each majority party in Congress, while nearly identical percentages were right about one of the chambers.
Familiarity with the House and the Senate is about the same in the poll. Nearly half the public (49 percent) named Democrats as the majority party in the Senate and half named Republicans (51 percent) as the dominant party in the House.
The Senate majority is up for grabs in the midterm elections, while the GOP's House majority is not in jeopardy. Republicans need to gain six Senate seats to win control of the chamber.
Among those who can name which party controls both chambers, 55 percent say party control in Congress matters to them a great deal. Only about a third or fewer of those who cannot are greatly concerned about party control.
