My take on Pete running is that his orientation would not be a very big deal.
1.) If you're anti gay in 2024
This is just me being an amateur sociologist and a chronically online one, but it seems like younger voters, who are neither hard left or hard right, aren't really concerned about being gay or straight, but they are obsessed with masculinity. Pete is way more masculine coded than Newsom. He speaks with bass in his voice. He loves data. If he ate some raw liver, he'd probably win over a few of the trad kids. If he said that his first act as president would be instructing the state department to refer to Istanbul as Constantinople, he's win all the trad kids. If he talks about how much he loves trains, he'd get every leftist under 30 on his side as well.
