Under a new anti-corruption plan Sanders released Monday morning, the progressive senator from Vermont is taking aim at money and influence within political parties, national party conventions, and presidential inaugurations. His plan would also scrap the Federal Election Commission and replace it with a new, tougher Federal Election Administration and attempt to overturn the Supreme Court ruling Buckley v. Valeo, which considers money the same as constitutionally protected free speech.

“When we win the Democratic nomination and defeat Donald Trump, we will transform our political system by rejecting the influence of big corporate money,” Sanders said in a statement. “Our grassroots-funded campaign is proving every single day that you don’t need billionaires and private fundraisers to run for president.”

The plan is focused extensively on getting corporate money out of the Democratic National Committee (DNC), a group Sanders clashed within 2016 after former top DNC staffers dismissed and derided his campaign. In his new plan, Sanders would ban corporate contributions to the Democratic Party Convention and its related committees, and he would instate a lifetime lobbying ban on Democratic National Committee chairs and co-chairs.

Sanders certainly has shown — twice, now — that he can run a presidential campaign without relying on corporate donations. His grassroots-powered campaign boasted the most money raised in the third quarter of fundraising among Democratic presidential candidates.
