Weren’t Millennials supposed to be Evangelical right wingers?
I do vaguely recall that talking point now. It was basically based on drawing trends from data points and assuming those trends would continue indefinitely.
Of course this fallacy shows up here a lot too.
Bush actually did win with young voters while loosing with old voters in 2000, but I suspect that’s because young voters feared Tipper and Lieberman, not because they liked Bush’s evangelicalism.
By 2004, it appeared that Republicans had peaked with younger voters and by 2006, they appeared to be crashing with them. The way that the Republicans have been able to win since then is a combination of voter apathy and pensioners swinging hard to the right as either i) the Overton window on social issues keeps expanding on the left or that ii) either the have been convinced that they "can't afford" new social programs/spending or that they are competing with new social spending to keep their pensions.
