Registered voters by age U.S. 2022 | Statista

Hi ,
Above is the percentage of the age demographics for voter registration.
I am sure if we looked at some racial groups , there would be differences there.

Any increase in turnout driven by increased registration will favour the democrats.
''Find me 18000 votes'' , suddenly becomes 36000 , if 18000 extra Swifties register in Georgia.

So relatively small movements in the battlegrounds , may allow celebs to have a disproportionate effect.
It may also be that this effect may be greater than in the past, because of the amplification effect of social media.

cheers
