After decades of constituting the majority of voters, Baby Boomers and members of the Silent Generation made up less than half of the electorate in 2020 (44%), falling below the 52% they constituted in both 2016 and 2018. Gen Z and Millennial voters favored Biden over Trump by margins of about 20 points, while Gen Xers and Boomers were more evenly split in their preferences. Gen Z voters, those ages 23 and younger, constituted 8% of the electorate, while Millennials and Gen Xers made up 47% of 2020 voters.

Biden barely won and a big part of it was record voter turnout from younger voters

The narrative that young people don't vote fell flat on its face in 2020

If by youth vote you mean Gen z yea still not great, and not to fall for the trap of saying millenials are young but those groups everybody scoofs at make up the majority of voters now.

The youth vote might not matter, but youth support does. They contribute labor to these campaigns that would cost incredible amounts if the DNC had to pay people.

Lol if you say so
