Democrats hold a four-point lead in which party American voters want to control Congress, according to the latest national NBC News/Wall Street Journal poll.
Forty-seven percent of registered voters prefer a Democratic-controlled Congress, while 43 percent prefer a GOP-controlled one.
In June, the parties were tied on this question, 46 percent to 46 percent, though Democrats held a four-point edge in May.
Republicans currently control both the U.S. Senate and U.S. House of Representatives.
The NBC/WSJ poll was conducted of 800 registered voters from July 31-Aug. 3, and it has a margin of error of plus-minus 3.5 percentage points.
