I dunno, I feel like the vast majority are fine with the pick, even if some are grumbling about it not being Warren or Bass. The fact that some of her biggest critics early on such as Shaun King are expressing their support now speaks volumes. The loudest people complaining about Harris being picked are the very online folks who Biden has been successfully ignoring during the campaign. If any lesson is learned from all of this its probably that Twitter isnt real life when it comes to electoral politics.
