I'd love to be wrong. Maybe there's a new level to Harris' game that will magically be revealed in the coming months.
I've followed her career since her CA days. Being a local DA is nowhere near the same level as running for President. As for the DEI issue, Biden literally broadcast to the world that he was committed to selecting a black woman VP, and he did. So instead of running away from it, the Dems should just own it, especially since they are the ones who champion DEI as good policy.
To be clear, she hasn't done anything in the past month either, other than selecting Walz and going on a short tour of swing states. Her momentum is reflective of the Democrats having a collective sigh of relief that their candidate isn't an 80 year old, and therefore a possibility that another Trump term isn't a forgone conclusion. It has nothing to do with Harris herself or anything she's said or done since she hasn't given a single interview and only released a bit of policy the other day. I can't recall a single situation in the past where people were asked to vote for someone going into a political convention without first knowing what their published policies are.
Back to my first line above - I'd love to be wrong. Maybe there's a new level to Harris' game that will magically be revealed in the coming months. So far I have not seen it.
