Donald Trump's national job disapproval rating has been nudging upward for roughly the last month, but only by a hair, from 52.4% on July 20 to 54% today (Aug. 27) in FiveThirtyEight's aggregate. But that narrow national window obscures a much larger and more important trend in key battleground states since the beginning of Trump's tenure. Indeed, Trump’s net approval rating has plunged in states such as Wisconsin (-14), Michigan (-11), and Pennsylvania (-8)—all of which Trump won in 2016.
