Since taking office, Americans' expectations of Donald Trump in regards to whether he would improve the way government works and set a high moral standard for the presidency have varied only slightly, a new Pew Research survey finds.

By the numbers: Prior to the 2016 election, 59% of voters believed he wouldn't improve the way government works, and 61% now agree with that. Similarly, 66% of Americans said in 2016 he wouldn't set a high moral standard, compared to 71% today who say he "definitely or probably not set a high moral standard for the presidency."
