He had a cabinet full of establishment insiders and not a vetted group. This time he seems to have a vetted group and better organized. Time will tell what comes of it, we can hope it will be good but we don’t know at the moment.
I think with how Harris had pivoted away from the zealotry prior to the DNC, to what she and others were saying during the DNC things may not have been as extreme but those insiders are chameleons - they change every day and you never know what you’ll get besides lies.
