Is there anything he can do to get any positive approval? I am not american but from outside point of view it seems like in every thread or news comments section it seems like even if Trump saved 50 babies from a burning house people will still find a reason to blame him and search for a bad motive.
Getting off Twitter would probably boost his approval by a couple points.
People can and will disagree with policies regardless of who or what is in office. But the way he conducts himself and the people he surrounds himself with really push people the opposite way, though at the same time it's distracting from some of his less agreeable policies.
This seems to be a distinction without a difference given how American politics works. You don’t need net positive approval to get elected, as evidenced by Trump’s current position as President. For this reason, it makes more sense in this context to say Trump does have positive approval from 4 in 10 Americans and the claim that “the world / media / etc” are wholly biased against him no matter what doesn’t hold water.
What do you think about that tim apple interaction? If you see proof that the president lies, to doners, and media, does that sow any hint that he is not honest? Credit is easy to lose.
A big part of his image, both admitted and admired, is essentially being an asshole. This is unusual, to say the least, and it can't be surprising that the reactions to this president reflect that.
