Faiz is essentially making the argument in that article.
Well it's great that I'm not making that argument.
I'm not saying that people shouldn't try to model the future. I'm saying that no one knows exactly what kind of youth turnout will be. 2016 was transformative in injecting energy in young voters. Data from 2016 and earlier will not necessarily capture that.
Reminder that Faiz's statement is in reference to a Biden vs Bernie in which there absolutely is a generational divide in opinion.
One of the core strategic pillars for the Sanders campaign is getting the highest young voters turnout ever. And Sanders have said multiple times that it needs to be even higher than 2018.
Past data is relevant to a point. There hasnt been a Black President until Obama. There has never been a Woman or Chinese/Indian-descent or a twin either but there might very well be one elected next year.
