But the Gavin and Michelle comes up all the time. - even though Biden is running.

No it doesn’t. At least, it’s not raised by any of the Corporate Liberals you’re directing your comments to. They don’t talk about Harris for the same reason they don’t talk about Newsone or Obama in 2024. Because they acknowledge that Joe Biden is running.

When other non-Corporate Liberal people are fantasizing about possible (fictional) candidates that might run against Biden, they will usually exclude Harris - because it’s unthinkable that a Veep could survive the damage to their prospects by declaring against their own running mate. Harris is already on the ticket with Biden. She’s the one politico in the country that can least run against Biden. Newsome or Obama (or anyone else not in the Administration ) can differentiate themselves from the Administration - Harris can’t, so she can’t run against Biden.

If Biden weren’t running, she’d be top of the field. But she can’t run against Biden, so the fervid fever dreams of someone entering the race can’t center around her.
