I agree, but they should just make the point once and move on. We know they're all DEI and virtue signaling, but it's just a distraction.
Attack her on all the failings of the Biden admin, including the cover up of his health. Attack the border, Ukraine, Afganistan, the econonmy.
It should be enough.
I think the point about her race swapping needs to be made but not made as the center focus of their campaign. You're right, they're just need to point out her history in CA and her time as VP.
Maybe throw out Montell Williams name once in a while too.

Speaking of the border, I was talking to a border patrol agent the last few days, he says they have been given orders to start prosecuting illegals that they catch crossing the border. He said it's all a political stunt because they have been forced to catch and release for the last 3 1/2 years and now they are going to try to deny that policy was ever in effect.
