“Joe Biden leads by around 9 points in our national polling average, and that lead has been growing. Of course, national polls don’t really matter. Otherwise, Hillary Clinton would have been president. But it’s worth noting that such a large lead is unusual in politics these days. Clinton never led by more than 7 points, for example, and at this point in the 2008 race, Barack Obama led John McCain by around 6 points.”
