What, specifically, does Newsom have as baggage besides the high crime of being governor of CA?

Nothing so much as he's a magnet for right-wing media to shit on. That can't be discounted because as we've seen every single time, the MAGAts love that crap, smear it around, and win elections wtih it.

(Edit: oh and being married to junior’s wife is going to be a thing)

Sure, I'd go for Stewart, as long as he could answer effectively about his SIMA policies.

I don't know what SIMA is? Apparently either search is so befucked it can't find somethign simple like SIMA or SIMA isn't known to it. Is it Steel trade agreements? That's the only thing I could see that was even remotely likely.
