Political writer Harry Jaffe this week released an unauthorized Bernie Sanders biography in which he highlights the Democratic presidential candidate’s populist appeal but also argues that Sanders’ dislike for foreign policy would make him a "lousy commander in chief."

Jaffe told InsideSources.com that he started following Sanders' political career as far back as 1976, as a 20-something newspaper reporter watching him in a Vermont gubernatorial debate.

“Nobody speaks the truth in a vernacular way to middle-class Americans who struggle every day to pay the bills, to the college graduates who have to find work and be self-sufficient and pay their college loans,” Jaffe said of Sanders.

However, Jaffee also writes in “Why Bernie Sanders Matters” that the Vermont senator and independent having to turn his attention to foreign affairs appears “painful” for him.

“Americans, while they may be interested in economics, also want to know that [presidential candidates] can be the commander in chief,” Jaffe said. “Bernie Sanders is a lousy commander in chief. He is not a trustworthy commander in chief to me. He is not somebody who thinks the military is the first order of business. Neither is Barack Obama.”
