What would a President Bernie Sanders do if he were elected in 2020?

The self-declared democratic socialist has been clear about his support of such policies as universal health care and free college tuition. But CNN found that when he first ran for the Senate in the 1970s, he advocated full-blown socialist policies such as nationalizing major industries, including energy companies, factories and banks. And he campaigned for a 100 percent income tax for the wealthiest Americans.

The network said Sanders’ “past views shed light on a formative period of his political career that could become relevant as he advances in the 2020 Democratic primary.”

The past positions, CNN observed, “could provide fodder for moderate Democrats and Republicans looking to cast the Democratic presidential candidate and his beliefs as a fringe form of socialism that would be harmful to the country.”

CNN noted that aspects of Sanders’ plans and time as a member of the far-left Liberty Union Party have been reported before, “but the material taken together, including hundreds of newly digitalized newspapers and files from the Liberty Union Party archived at the University of Vermont, paint a fuller portrait of Sanders’ views on state and public-controlled industry at the time.”
