AP Norc poll has him at 39%. Now another: ABC Washinton Post:

Thirty-nine percent of respondents in this ABC News/Washington Post/Ipsos poll said they approve of how Trump is handling his job as president, down 6 percentage points from February, while 55% said they disapprove.
Trump’s 41% approval rating is the lowest for any newly elected president at 100 days dating back at least to Dwight Eisenhower – including Trump’s own first term.
Approval of Trump’s handling of the presidency is down 4 points since March, and 7 points lower than it was in late February. Just 22% say they strongly approve of Trump’s handling of the job, a new low, and about twice as many say they strongly disapprove (45%).
What are the GOP congressional and Supreme Court majorities going to do now? Will they just go full fascist to maintain power or will they challenge him to save themselves?
Stay tuned.
