Trump approval in polls currently showing Trump at say, 43% will probably increase to 50-53% in the following days due to the favorable Mueller report finding no collusion
I will provide updates as the polls come out.
The fact that Trump didn't knowlingly collude with Russian doesn't change his performance since being President. In many ways, it makes his behaviour look much, much worse. Why lie, if you've done nothing wrong? The fact that he has carried on like a loon over the Mueller Investigation makes him look ridiculous.
This exposes Trump as a coward and a total snowflake. "They're picking on me. It's so unfair." Instead of "Russia interfered in our elections and we needs to get to the bottom of this". Trump didn't care what it did to the country, he only cared about himself. That hasn't changed. And he labelled an investigation into the most egregious interference by a foreign power into an American election a "witch hunt", when he should be doing more to prevent it from happening again in the future.
But the real reason Trump's approval rating won't go up is because his approval rating is based on his actions and his policies as President. Policies like separating families. Like his trade war with China. His hate speech against non-whites and non-Christians is an embarassment to the majority of the American people. As is his treatment of others.
He cannot get staff to work for him. He publically abuses and humiliates those who give him the honor of accepting his job offers. And he coddles toadies and "yes men", emphasis on "men" because none of the advisors he listens to are women.
This past week, flooding in the mid-West, washed away and destroyed the crops farmers couldn't sell last year because of Trump's trade war, further undermining and undercutting mid-Western farmers who trusted Trump when he started his trade war with China, and for whom taking government handouts into the billions and billions of dollars will now be their only salvation, and no end in sight to this trade war.
Trump celebrating his "victory", while working Americans, farmers, and the middle class have little to celebrate because of his policies, won't go over well.
