Is the Democratic National Committee looking into the possibility that Hillary Clinton will step aside? Or will it perhaps even force her to?

Cokie Roberts said on NPR’s Morning Edition on Monday that Democrats are “angry at the lack of transparency” after Clinton’s collapse on a New York City street on Sunday.

“It was hours after the pneumonia diagnosis was revealed after seeing this incredibly damaging video of her being helped and stumbling into a van,” Roberts said.

“Look, there’s a reason why the campaign’s not transparent, obviously, it gives Trump ammunition and he’s been setting her up for this for months.

“Back in January, he started saying she didn’t have the strength and stamina to be president and he knew at some point that she, like all candidates, would get exhausted,” Roberts said.

“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, canceling her trip to California today.

“It has them very nervously beginning to whisper about trying to have her step aside and finding another candidate,” Roberts said.

Her statement seemed to floor the Morning Edition host.

“That is no small thing to say. I mean, is that a real thing?” he said.

Roberts replied it was “unlikely to be a real thing,” but continued, “I’m sure it’s an overreaction from an already skittish party.

“But you know, they have looked at what happens in that circumstance and the Democratic National Committee chair convenes the committee and they vote,” Roberts said.

“Now, ironically, the candidate everybody looks at is Joe Biden, who is older than Hillary Clinton,” she said.

Roberts added “we assume” Clinton will resume her schedule as the campaign claims.

“But there is enough unhappiness that this kind of,” talk is going on, she said.

Roberts’ statement is an extension of what former MSNBC and Al Jazeera anchor David Schuster reported on Sunday.

In a series of tweets, Schuster said, “Expect emergency DNC meeting to CONSIDER replacement.”

He also quoted an unnamed “top Dem” saying the party can “plead” with Clinton but that “DNC bylaws are clear her nominee status now totally up to her.”
