Is there any polling more meaningless than "congressional approval"?
Conservative: "Hey, I'm pissed that Congress can't get any of it's bills past the Democrat-controlled Senate and WH! I'm going to vote for more Republicans!"
Libtard: "Hey, I'm pissed that the Republican-controlled House won't compromise with the Senate! I'm going to vote for more Democrats!"
Pollster: "Welp, there you have it, 88% agree that Congress sucks."
