On NPR's Morning Edition on Monday, ABC News contributor and columnist Cokie Roberts said that Democrats are "nervously beginning to whisper" about what might happen if their nominee for president Hillary Clinton has to step aside for health reasons. "They have looked at what happens in that circumstance," she said.





COKIE ROBERTS: People are angry at the lack of transparency -- it was hours before the diagnosis of pneumonia was revealed -- after seeing this incredibly damaging video of her being helped and stumbling into this van.



Look: There's a reason why the campaign is not transparent. Obviously it gives Trump ammunition, and he has been setting this up for months. Back in January he said that she didn't have the strength and stamina to be president. And then he knew at some point in the campaign schedule, she, like all candidates would get exhausted. But the fact that it comes now, when the polls are tightening and Democrats were already saying that Hillary was the only candidate who could not beat Trump, and it’s taking her off of the campaign trail,cancelling her trip to California today. It has them very nervously beginning to whisper about her stepping aside and finding another candidate...



I think it’s unlikely to be a real thing. I’m sure it’s an overreaction about an already-skittish party, but you know, they have looked at what happens in that circumstance. The Democratic National Committee convenes the convention, and they vote.



Ironically the candidate everyone looks at is Joe Biden, who is even older than Hillary, and then again, so is Donald Trump.
