I'm not sure how this data was compiled or modeled, but the person who posted it is very smart and I trust that its in the ballpark... Keep in mind its only Whites, and a big part of the story is that younger generations are far less white than older ones.
https://twitter.com/davidshor/status/943949883165302789The claim that Generation Z was going to be outright right wing was always cherry picking / nonsense, but they might be a bit more conservative than the tail end of the Millennials (at least those born in the mid 90s).
I think there's some polisci research that states that its around the age of 18 that partisanship/political beliefs lock in most strongly. If that's the case, this graph makes perfect sense... the most Democrat leaning ages are people that turned 18 either in Bush's second term when he was extremely unpopular, and in the first couple of years of Obama's presidency. Based on this, I would also fully expect persons born in 1999-2002 to end up being quite a bit more Democratic than those born from 1996-1998 or so...
