I’m not sure this is great news, although I’d rather have 65+ voters over the under 30 crowd. But judging by most polls those are the two groups most likely to vote Biden. It’s the 30-64 crowd that is heavily supporting Trump.
GenX/Millennials have always been the Dems base. It's bad news for Biden all round.
And the black voter turn out is very low in NC and Florida as well.
Biden is going to get the lowest black vote for a Democrat in recent times. Low energy Joe just can't inspire anybody.
