Ten years ago this week, Sen. Bernie Sanders (I-Vt.) ended his first presidential run and endorsed Hillary Clinton. Now, his chief strategist says the primary process was rigged.

Today on Lever Time, David Sirota sits down with Tad Devine, longtime political consultant and chief strategist for Sanders’ 2016 presidential campaign. Devine reveals why he believes the Democratic National Committee tilted the scales against Sanders, why his populist message has staying power, and why the biggest obstacle in future elections is the Democratic Party itself.

Check out Devine’s book, How The Democrats Screwed Bernie.
