We'll see for sure I suppose if it comes to pass but Biden was unsurprisingly all talk and no bite with so many of his campaign promises (especially his Youth ones like the environment and maybe the biggest F YOU to the youths if he decides to restart student loan payments in the next few months). I do not think that Gen Z is going to accept another round of "This election is too important to let THEM win but we promise NEXT time, we'll totally make sure to focus on what you want, pinky swear".This might work again if Trump is the nominee or if the nominee can manage to inspire a similar degree of terror to turn out the vote. The election is won or lost by Dem turnout more than anything - there are more Dem voters, enough more that if they'd just go out and fucking vote consistently the GOP would have very few seats at any level. Even after gerrymandering, because the gerrymandering assumes a predicted level of turnout for each party - you only have so many people to draw lines around and the more seats you take by drawing clever lines the narrower the margin you have to engineer around and the easier it is to overcome by raw turnout.
Although plenty of other generations have sucked that line down and asked for another helping so maybe I'm giving Gen Z too much credit.
