Clinton can’t crush peas with her teeth. Trump would steam roll her completely. She would end the race for medical reasons.
Trump won’t back down and play nice like the liberals that ran as Republicans the last two times. Trump won’t accept losing like mclame and mitt did.
I doubt whether she would be willing to debate Trump, should he be the GOP nominee. He would destroy her in a debate setting; she would probably claim that it would be beneath her dignity to go one-on-one with such a coarse and vulgar opponent.
