I don't trust him and probably never will, but I do admit he's at least charismatic. He'll be able to navigate not being a straight white man. Anyone he can't charm to see past that wasn't going to vote for a Democrat in the first place. It's the same reason AOC being a woman isn't a problem.
Buttigieg also had the veneer of forward thinking progressivism before he turned moderate because Bernie and Warren had filled that lane (why I'm never going to trust him). So he can also give lip service to big change like Obama did too. He just doesn't believe any of it.
Like Obama he's nicely packaged but too enraptured with the idea of power to actually meaningfully pursue change. And we can't keep turning to painkillers when we've got these increasingly infected wounds. When you leave things like Guantanamo to fester because it's just too hard and you want good vibes, they open the way for lawless concentration camps at home.
A strongly worded letter! Whatever will they do?
