Levin: 'Embodied the best of who we are' Former Colorado Gov. Richard Lamm dead at 85 MORE said Tuesday's failed cloture vote on a military policy bill has strengthened Democratic hopes to change the chamber's filibuster rules next year.

Levin said the 56-43 vote on a Defense Department authorization bill should have passed even though Republicans blocked it.

"I don't think a filibuster before has ever prevented the Senate from getting to a defense authorization," Levin said. "These filibusters on motions to proceed cannot be allowed to prevent us from getting our work done."
