Just a wild guess.
They could roll out Blowprah to endorse her and have BootyGig as VP.
Blowprah has a Weinstain problem, she was his pimp, would recruit all the young wanabe starlets to meet him for movie gigs/for sex trade
She would get destroyed, it is why she has been hanging low.
Michelle values her self image more than anything. Going up against Trump is going to destroy that, she will get a Trump name, Trump isn’t afraid to blast all her life failures including the lousy school lunch program. And he would have zero problems tying her to her husband and all of his great failures.
Michelle wants to run, but not in 2020, but in 2024 she will pop out.
Biden, Bernie, Warren, Klobachar, Bloomberg are all hasbeens that probably won’t run again in 2024
Buttyboy is in it because, well, what does he have to lose? Seriously, this has elevated him on the national platform, he has nothing to lose at this point. Even if he doesn’t get the nom, he is looking to be a CNN/MSNBC contributor, book deals, speaking etc, from failed small city mayor to national figure is a giant jump and a better pay day.
Booker and Kamala left the race because 2024 looks more promising to them
