It is absolutely stunning to me that the Ukraine impeachment stuff has had zero effect on his numbers
I'm not sure how many times I have to post this:
Trump is always at or around -10. Sometimes he goes above that, sometimes he goes below that. But his numbers always return to the -10 range.
He was considerably below that for his first 14 months before climbing up to the -10 range he has been steady at since then. The only notable thing I can think of in that time frame to account for the increase would be his much-hyped but currently near-complete failure negotiations with North Korea.
