Started, IMO, when Bidan announced heels up was going to be in charge of the border mess.
Harris can't control that psychotic, inappropriate laugh she has and fhe promptly fucked everything up by laughing about the crisis before she even got of the gate.
Trump pounced, saying he was going to the border. That would have set up a long distance sound bite tit for tat, Trump vs Harris, and the suits immediately pulled Harris.
My guess is there was going to be some kind of press snow job to make it look like Harris "solved" the border problem, and that would have started the campaign to convince the peeps Harris was ready for the WH.
Trump fucked them up. Goal may be to get Bidan and Harris unscripted replying to Trump criticism. Psucki can't even pull that off without looking like an devious dipshit at a scripted PC, so Bidan or Harris would have the country ready to run them out of town on a rail if they spoke off the cuff with the media where some Trump friendly reporters or outfits were present.
Target is Harris, though, I think, and the military draws the line and shuts down this shit show if Harris tries to go to the WH, Trump might be prepping the battlefield for the military exposing her. She won't be allowed to have the media cover for her, or run a scripted snow job trying to put lipstick on the pig.
Trump isn't blowing smoke with his WOKE criticism. Peeps are tired of the bullshit and Bidan/Harris have nothing to counter with off the cuff and will just make it worse.
