... and a successful author, etc. It’s one thing to lose as someone else’s running mate. When she loses on her own, all that popularity will quickly dry up. Her publishers know it. She likely knows it. She’s be derailing her own gravy train, and she would then be without influence.

The counterpoint to that argument is that she only has influence now because she's a potential candidate. If she takes that off the table, she'd have no influence or "gravy train".
