The latest survey from The Economist/YouGov this week found just 38
percent of respondents approved of the job Trump has done in office.
That's a new low for the president in The Economist/YouGov weekly
tracking poll.
Perhaps even more importantly, Trump's "strong approval" rating has
fallen. Compared with last week, those who selected "strongly approve"
fell 2 percentage points, to 17 percent, according in The
Economist/YouGov poll.
Trump's true base—those who approved strongly—has shrunk from about 30
percent of the electorate in February to just about 20 percent in May.
