Again, you’re only acknowledging the existence of data that lies within the duopoly.
I'm acknowledging turnout in the last election cycle. Third parties did not notably over perform.
Yes, young people are rejecting the GOP, but that has not translated into gains for the Dems
Young people haven't been rejecting the GOP either. Republicans are getting about the same percentage of the youth vote as they have over the last twenty years.
Dems lost votes across the board in '24. It wasn't unique to young voters. Republicans gained slightly relative to 2020. It was not an otherwise noteworthy election with regard to turnout.
