If she's running against Trump, I think it's a great idea.
Think about it: she's at least as experienced, if not more so, than Trump is. She hasn't declared bankruptcy a million times. Hasn't been married 3 times with 5 kids - think of the SS savings.
She's empathetic, intelligent, well-read, likely to study hard for the job, generous, and most of all, middle America loves her.
Her popularity is such that there's no tacky nickname that Trump could throw at her that could stick without him being torn apart by said-middle-America.
She may just be the perfect candidate to foil him.
