What if something happens to Hillary Clinton? After her last presidential campaign faltered in 2008, the question among liberals is being asked openly.

Although Hillary Clinton continues to lead in the polls, according to former Obama environmental adviser Van Jones, it’s Elizabeth Warren’s name that’s “on the lips” of grassroots voters and not the former First Lady’s.

“What happens if something happens to Hillary? The Democratic bench is pretty weak,” host George Stephanopolous asked Jones.

“We have talked about gender. We talked about a couple of other names. Elizabeth Warren, that’s the name that is on the lips of every grassroots Democrat,” Jones said.

“But she’s not running!” Stephanopolous said. “Her media adviser went to Hillary Clinton this week.”

Jones told the ABC News anchor that the Ready for Warren movement has hundreds of parties going on this weekend at the grassroots level, where, he said “people actually matter…where people actually vote.”

“There’s thunder on the left. Hillary Clinton has to deal with, she’s in a different world when it comes to economics. Post-Occupy Wall Street. Income inequality is a big issue. Mitt Romney is talking about it,” Jones said. “She’s now gotta get her head wrapped around — there’s a Democratic Party very comfortable about talking about the middle class. Very comfortable talking about tax the rich. How does she relate to that.”
