 Two weeks 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. 85% 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% of his own supporters now say he should step aside.
