Congressional approval is up 50% from September. Why do you think that is?

Well, looking at all the graphs and statistics, it would seem that congressional approval correlates with approval of an impeachment inquiry. In other words, in general, people are saying that they approve of Congress because it is finally doing its job. 

Democrats who are ARITHMETIC deficient are not my problem. Congressional Democrats included unfortunately.

So it went up to like 2% now?

They must have polled a lot of ignorant people, those who only know what the liberal media tells them.

Literally the first thing I saw in your link.

"25% approve of Congress"

That's nothing to brag about.

When the approval rate is 10, another 5 is still only 15. You must be a democrat.

Well, Congressional approval is so ridiculously low it's pretty easy for it to increase by pretty big chunks.  I think it also helps that people can see that Congress is actually doing SOMETHING whereas the usual idea is that they do nothing.
