The chart above reflects the results of a recent Rasmussen Poll -- done on November 21st of a random national sample of 1,000 likely voters, with a 3 point margin of error. It shows the 115th Congress, controlled by Republicans, is still extremely unpopular with the American public. Only 13% approve of the job this Congress is doing.
Those are terrible numbers, and unless the Republicans can improve them, could signal a wave election in 2018 (which could flip Congress to control by Democrats).
The Republicans are trying to ram through a tax reform plan. They seem to think that will save them in the next election, by convincing voters that the plan will actually benefit most Americans. But it won't. It's basically a huge tax cut for the rich and corporations -- at the expense of all other Americans.
And it looks like the public knows that. Only 29% of Americans approve of the odious GOP tax reform plan (see chart below).
The bottom chart is from the latest Economist / YouGov Poll -- done between November 26th and 28th of a random national sample of 1,500 adults (including 1,319 registered voters), with a 3.2 point margin of error.
