CNN's polling analyst, Harry Enten (formerly of FiveThirtyEight), takes notice:
"A new ABC News/Washington Post poll puts President Donald Trump's approval rating at just 36%. An IBD/TIPP poll also puts the President's approval rating at 36%. Finally, a Kaiser Family Foundation poll gives Trump an approval rating of 37%. All three are declines from the last poll by each pollster, which had Trump's approval rating in the low 40s."
ABC/WaPo's polling receives a grade of A+ from Nate Silver. IBD/TIPP's polling receives an A-. Silver has not graded the Kaiser Family Foundation's surveys, probably because of their wide-ranging partnerships (with WaPo, the Economist, etc.). At any rate, the above polls, all respected, almost certainly suggest a significant downward trend for Trump, although his "approval rating did not shift in Gallup's weekly tracker," adds Enten.
As significant as the polls' spiraling numbers is the timing of these polls. After running through gobs of statistical reasoning, Enten concludes that "For Republicans to have a realistic … shot of maintaining control of the House in 2018, Trump's approval rating must remain at least in the low 40s nationally."
The GOP's "shot" is losing steam by the day, and for that we must say, Thank you, Mr. President — in doing everything wrong, you're finally doing something right.
