The top strategist for Sen. Bernie Sanders (I-VT) floated the idea Monday that Sanders could be a running mate for former Secretary of State Hillary Clinton even as he added that no one is talking about that in the throes of a primary battle.

During an appearance on Politico’s Glenn Thrush’s Off Message’ podcast, Tad Devine suggested that one way Clinton may be able to make up ground with young voters would be to add Sanders as her running mate.

“I don’t know. Maybe they’re going to put him on the ticket then,” Devine told Politico as he laughed.

Devine added that Sanders, like anyone, would consider being Clinton’s running mate, but he added: “I don’t think there is any plan for that.”

“He wouldn’t ever think about a decision like that unless it was done in the right and proper way,” Devine said.
