A new ABC News/Washington Post poll released this weekend shows Joe Biden leading Mr. Trump in the suburbs by a margin of nine points. In 2016, suburbs powered his victory, with exit polls showing he won them by four points. In fact, Republicans have lost the suburbs only three times since 1980: In 1992, 1996 and 2008 — all three, Democratic wins. Mr. Trump won the suburbs of North Carolina by 24 points, according to 2016 exit polls. In Florida, a state that was expected to favor Mr. Trump, a 10-point advantage in 2016 exit polls is now a six-point deficit.
