I see people quoting invalid statistics.
The math: Let me show you.

I saw someone earlier saying that only 12% of the young voted, and that blacks did not vote.
These statements are both false, and both the fault of bad communication from journalists.

White people over 45 outvoted their demographics BY FAR. And these people lean republican. Whites as a whole voted 60% Republican. They don’t break out age plus race plus vote, but it’s going to be higher than 60% for older whites, verifiable by the numbers.

This info pertains to US demographics overall, not only registered voters.
(Note there’s a tiny bit of potential error in the Demographics number, as a few educated estimates had to be made.)
Demographic info from the census, wiki.
Voting info from the Post, exit polls.
