Donald Trump's approval ratings have been moving down again over the last three weeks, and Tuesday he finally broke through to a new low of 37.8 percent approval in FiveThirtyEight's daily estimate, just a bit below the previous floor at 38.0 percent. The other polling aggregators tell much the same story; the RealClearPolitics average has him at 39.2 percent and just above his all-time low, while the Huffington Post estimate is 38.7 percent approval, a low. Disapproval has spiked up, to a Trump high of 56.7, according to FiveThirtyEight; the other aggregators tell much the same story.
Using the FiveThirtyEight numbers, the new low -- which might turn out to be a one-day fluke -- ends an 11-week string in which his approval floated between 38.0 and 39.9 percent, giving new ammunition to those analysts who believe that partisan polarization gives Trump a high floor. Indeed, RealClearPolitics' David Byler published a perfectly fine item Tuesday morning speculating about why Trump's approval was so stable.
