I don’t think he will go this far. I think most the crowd would not welcome his presence, and Dems would get a lot of flack. Also, since he left office, he seems to want a low profile. I don’t think he wants the attention.
TMZ reporting Beyonce’ will perform at DNC (might be a pre-recorded song/speech). Kamal/Walz does use her Freedom song.
Taylor is a pretty savvy businessperson.. doubt she would endorse Kamala.
Of course a performance vs endorsement are two different things.
And you wouldn’t think Harris camp would want to overshadow her big night.. but maybe that is the plan.
