Since his inauguration, Donald Trump’s net approval rating — already at a historic low for an incoming president — has taken a further hit. According to the Pollster average, about 50 percent of Americans disapprove of the job Trump is doing as president while 43 percent approve, for a net approval rating of -7. In Gallup’s polling, Trump’s net approval is -10.
