New book, "How the Democrats Screwed Bernie," argues party establishment tanked Sanders in 2016

Tad Devine, the chief strategist for Bernie Sanders' 2016 presidential campaign, argues in his new book that members of the Democratic Party's establishment conspired to prevent Sanders from capturing the nomination. The book is called "How the Democrats Screwed Bernie." Devine joined "The Takeout" to discuss.

Tuesday’s primaries are setting the matchups in around a half-dozen competitive House races that will be key to the fight for the House majority in November, including in a hotly contested Democratic target in Wisconsin.

Sen. Bernie Sanders (I-VT) wants super PACs banned from having a hand in Democrat primary elections, namely the American Israel Public Affairs Committee (AIPAC).

Sanders believes that even candidates who support super PAC reforms will continue accepting money from super PACs for use in elections so long as there is benefit to be gained from the arrangement.

Sanders is urging Democratic leaders to ban super PACs from party primaries, citing concerns about outside spending and influence.
