Leading in what? Delegates? State polling? Do any of them even have independent state polling? Or field offices? Any lawyers to get them on the ballot in each state? Do any of them have a fundraising apparatus? Campaign staff? None of them have any meaningful name recognition outside of their home states. Newsom is the only one getting national press coverage, and that's because the right wing likes to burn him in effigy.

Like I said, I would love to see all of them in an open-field primary next time around. I'd much prefer a better candidate than Biden. But you're dreaming if you think someone else can step in now and actually win. If Biden is alive, he's on the ballot. If he happens to die, the DNC will make sure it's Harris.
