The polls dont mean a damn thing until they start accurately reporting GenZ and Millennial voters. These two demos voted overwhelmingly Democratic the last two elections (30+ points), turned out near 5-10% higher the last two elections than the next highest turnout in 30 years, and they have been vastly and even incorrectly underrepresented in polls. It also doesn't help with these groups when your policies are pretty much the opposite of what you would want if you are young, sexually active, social media consuming highly individualistic and empathetic young people.
Also the GOPs current tactics of making it harder to vote in every conceivable way doesn't impact these two demos as they are just as capable of mailing in as they are standing in line in the one precinct allotted to them on their college campuses, even with a 5 hour wait, lack of ballots, inability to provide or receive water/snacks from poll workers. They will vote.
I'll add that if the GOP has any hope of offsetting the huge overall voting gap its gonna have to come from the Hispanics.
but also GenZ set to be most educated demo (TOO WOKE!)
