I listened to it and I think that it's way off the mark. Blaming the Chi-Coms for the shortcomings of the rvp is just looking to deflect root cause.
The rvp could have done the same but pretty much sat on their hands in the population centers. Red county turn-out in Virginia was historic this go-round but simply put, land don't vote.
Take my small red county as a example, we actually gained ground on the dems by a couple of percentage points this go-round and that had shit-all to do with the rvp, they were, for all practical purposes, non-existent in my county.
Hell, I had to go to another county (Shenandoah) just to get Trump yard signs. Seems they spent all their money paying for lawyers to defend one of their guilty as fuck cronies from a maleficence while in office lawsuit.
The bottom line is that the dems stole a registration march on the rvp in the population centers like NOtVA and then got them to the polls on top of it. No matter where their backing came from they put in the work and got the end result they worked for.
