*By Christian Smith* Bernie Sanders is considering another run for president in 2020 the Vermont Senator's former campaign manager said. "He's actively considering it. He hasn't said yes. He hasn't said no," said Jeff Weaver, who ran Sanders's 2016 campaign. "I think going into 2020 he will take a hard look at whether he would be the person who is best able to beat Trump." Sanders won't have to declare his intention to run for president for at least another year, but the septuagenarian socialist firebrand announced early Monday that he will seek re-election to the Senate this November. Sanders [tweeted](https://twitter.com/BernieSanders/status/998573429946245120) that he plans to run a grassroots campaign with modest fundraising goals, which is the same strategy he used to challenge Hillary Clinton for the Democratic nomination for president in 2016. That campaign is at the heart of Weaver's new book, "How Bernie Won: Inside the Revolution That's Taking Back Our Country-and Where We Go From Here." In the book, Weaver, a longtime Sanders aide and adviser, discusses the progressive candidate's lasting impact on the Democratic Party. "It's been changed immeasurably," Weaver said. "The rank and file of the party wants a bold progressive vision. They're very excited about it, and we need to make sure that the sort of party insiders and some of the establishment folks get that." Weaver, who is still involved with Sanders's campaign, said that the popular embrace of "fringe" policies like a $15 minimum wage and universal health care are examples of Sanders's victory. "The debate in this country has really moved away from the sort of rightward drift that the Democratic Party was undergoing over the last 20 years," Weaver said. Sanders, who was first elected to Congress in 1990, has long been considered one of the most progressive members of Congress. The Democratic party is finally catching up, Weaver said.
