The public didn't like the 114th Congress, giving them low ratings throughout the two-year term. If Republicans, who control both houses of Congress, were hoping the 115th Congress would be viewed differently, then they are in for a big disappointment. It seems that the American public has just as low an opinion of the new Congress as they did the old one.
This is verified by two new polls -- YouGov gives Congress an approval rating of 12%, while Gallup gives them an approval rating of 19%. And in both polls, that low approval stretches across all political groups.
The Economist / YouGov Poll was done between January 7th and 10th of a random national sample of 1,424 adults (including 1,237 registered voters), and has a margin of error of 3.1 points.
The Gallup Poll was done between January 4th and 8th of a random national sample of 1,032 adults, and has a margin of error of 4 points.
