This is really good messaging. Newsom is a really good orator and has a lot of charisma. He'd be a force to be reckoned with if he ran for President.
Who says Harris is going to be a serious candidate in 2024 or 2028, much less the frontrunner? She's a disaster.
Buttigieg is more likely at this point. It's clear the Biden administration appreciates him more, and for good reason (see: 2020 Democratic presidential primaries). Harris? C'mon, man!
