And even though support for withdrawing has dipped since the spring, those who disapprove say it’s because the situation wasn’t handled well — more so than they think troops now ought to stay. Moreover, Americans mostly blame the Afghan government and its army for the Taliban takeover.

Mr. Biden gets a net negative rating for handling the withdrawal, with mainly Democrats backing him here and a substantial drop since July.

Mr. Biden’s overall approval rating, which had been consistently net positive since he took office, has dropped eight points and now lands at an even 50-50 nationwide.

He takes a big hit among independents. They’d given him positive marks in July, but now, more than half disapprove of how he’s handling both withdrawing from Afghanistan and his job overall. His overall approval is down within his own Democratic Party — it’s still high, in the 80s, but off its highs in the 90s. And while he had enjoyed a bit of Republican approval through the summer, that has dropped.
