Zelizer CNN article: VP
"Of all the contenders for vice president, Warren has one of the best chances of mobilizing progressives within the party. Without having to compete against Sanders, Warren can represent the left wing and serve as a unifying force on the ticket. She is an unabashed supporter of using government to solve problems and she has consistently put forth policies that progressives agree with."

"Warren has something else to offer. She became known for having a plan, or what seemed like an answer for every problem. She thought systematically about the nation's challenges and laid out detailed responses. At this moment, Americans are desperate for a plan. Somewhere in between the choice of permanent self-distancing and reckless liberation must come a well-thought-out plan that is comprehensive and clear."
