You can only fail for so long in so many areas before people start to notice.
According to The Hill:
Biden had enjoyed a steady approval rating in the low 50 percent range for most of the first seven months of his presidency, according to a FiveThirtyEight average of polls. The president was buoyed by a stable economic recovery, declining coronavirus infections and deaths and early policy accomplishments like the passage of a $1.9 trillion stimulus package.
But things have taken a turn for Biden in recent weeks. His approval ratings began to take a hit amid the messy withdrawal of U.S. forces from Afghanistan and the subsequent ISIS attack in Kabul that killed 13 American service members.
A Quinnipiac University poll released last week found 42 percent of participants approved of Biden’s overall performance, with his approval on foreign policy dropping significantly.
On Wednesday, Biden’s approval rating sank to its lowest number yet in the monthly Gallup poll, with 43 percent of Americans giving him positive marks, down 6 percentage points from August.
Biden’s approval in a Morning Consult poll fell from 51 percent in early August to 48 percent at the end of the month — though that number is at least close to 50 percent.
