I doubt it. Millennials don't look to be moderating or shifting their views anytime soon and they're gonna make up an even bigger share of the electorate in 2020 and an even bigger share than that in 2024.
Virtually every Millennial could vote in 2016, the only ones that couldn't were the youngest 2-3 years of it. 2000-2001 and later is Generation Z, which is much more conservative than Millennials are. Gen Z kids are too young to remember Bush and virtually all were born after Clinton, so their actions and policies have absolutely zero resonation with them.
Yeah, but being able to vote isn't the same thing as being likely to vote. People are naturally more likely to vote as they get older, so more and more millennials will be showing up to the polls one way or another. Also, the more old people die, the larger the share of the electorate that millennials make..
Yes however the older people get the more conservative they get so these millennials will become just like the rest of Americans
