 Since the debate, the ABC News Washington Post-Ipsos poll finds two-thirds of Americans believe the president should drop out. That, even as the same poll shows the race is still effectively tied nationally with a one-point edge for Donald Trump. Eighty-five percent in the survey say Joe Biden is too old for a second term. Most Americans say the same about Trump, but Biden is ahead on that score by 25 points. And 54 percent of his own supporters now say he should step aside.
