Going back to President Truman in the 1940s, President Trump’s approval rating has shifted less than any other sitting president. At its peak, Trump’s approval rating is 47%, at its trough it’s 38%. Obama’s approval rating was the next most stable, swinging just 16 points, and Clinton’s followed, swinging 19 points. This suggest we increasingly view our presidents through the party they represent rather than the job they are doing.
