By any metric, Trump is in trouble.

A poll out from The Post and ABC on Friday shows that 60 percent of voters disapprove of the job he’s doing as president, a new low. But that’s just one poll; the polling average at statistician Nate Silver’s FiveThirtyEight shows Trump with a mere 53.4 percent disapproval rating, which is better than its 56.8 percent peak last December.

But a presidency is not in good shape when the best spin on the new poll is “It’s an outlier! Only 53 percent of the country thinks the president is terrible.” The poll is especially ugly for Republicans with midterms looming in two months.

FiveThirtyEight’s forecast for the midterms puts the likelihood of Democrats taking the House at more than 70 percent. Their chances of taking the Senate are lower, but Republicans are hardly a lock despite a very favorable map for them. And if Democrats manage to eke out a majority in both houses of Congress, here is the poll’s really bad news for Trump: Half the country wants him impeached.

To put that in perspective: In January 1974, well into the Watergate scandal, Richard Nixon’s poll numbers on impeachment were better than President Trump’s are now. Earlier, less disastrous polls for Trump still showed him veering dangerously close to what we might call “the Nixon ceiling.”

Most worrying for Trump is that three-quarters of Democrats say they want Congress to impeach him. If Democrats gain control, they will be under immense pressure from their base to deliver.
