I don't think we can even blame this just on boomerism though, the average age for candidates didn't go up a little, it went up a LOT. Obama finished his final term as President just over 6 years ago, and he is only 62 right now. Trump is 77 and Biden is 80 right now, a year out from election day. That's not "boomers voting for boomers". Trump is just barely a boomer at all, and Biden is solidly silent generation.
