She’s more ready than Trump is who was already “president.”
That said, I would rather her be in Congress longer because she can be a voice longer. After 8 years of being president if elected, she wouldn’t then want to become a senator or whatever. That would pretty much be it for her in politics outside of ex-president things… and she’d only be 43.
I’m also sure Kamala would be pissed if AOC were to get the nom instead of her. Not that that matters.
