“With Joe Biden claiming almost a double-digit lead in national polls, one question still seems to loom over the race: Can we trust the polls after 2016?
It’s a good question. But for now, it’s not as important as you might guess. If the election were held today, Mr. Biden would win the presidency, even if the polls were exactly as wrong as they were four years ago.
The reason is simple: His lead is far wider than Hillary Clinton’s was in the final polls, and large enough to withstand another 2016 polling meltdown.”
