Based on the strong language Joe has been using, I don't think there is any chance, right now, he will willingly step aside. I think the 25th is only way to get him out of the way. But doing that will short circuit this elitist, anti-democratic plan to hold a beauty pageant to anoint a replacement. Enacting the 25th gives Kamala the keys and the leverage. With the right VP pick, she might swing a couple of endangered blue states back in her column, but I think her dismal record on the border, her having to defend the Biden/Harris economic policies, and complicity in the Biden cover-up will still spell disaster in November for the dems.
