For all the the media and pollsters saying that there is more Republican EV participation than in the past, based on Georgia Data, that appears true. Except, that's not the full story, essentially speaking they are talking out of 2 sides of their mouths. Yes, EV likely Republican returns are in fact higher, as the data dump last night 6.3% of people that voted day of 2020 (likely Republican) have now voted early. But 6% of more participation doesn't remotely reflect the at least 25% bump in EV we are now projected to have here.
Of course every state is different, so results may vary. However, the truth, at least as Georgia is concerned, is this, previous non voters and indy's are driving this; ie. previous voters with low engagement. Now not all of that vote will break the Harris way, but I'd bet more of it does than doesn't. I strongly suspect that this is going on everywhere.
When this is all over, and the pollsters and media (which will do nothing but blame the pollsters) all have egg on their face, one of the things they will point to is over-representation of Republican voters, and under representation of low engagement of previous non participants.
