Bernie Sanders urges left to back Biden to stop ‘very dangerous’ Trump

Leftwing senator advises unification of progressive people in general' because threat from Republican ex-president is too great

Progressive US voters must unite behind Joe Biden rather than consider any of his Democratic primary challengers because the threat of another Donald Trump presidency is too great, Bernie Sanders has said.

We're taking on the ... former president, who, in fact, does not believe in democracy - he is an authoritarian, and a very, very dangerous person," the senator and Vermont independent, who caucuses with Democrats, said on NBC's Meet the Press. I think at this moment there has to be unification of progressive people in general in all of this country."
