How Bernie’s Campaigns Reorganized the Organized Left

A decade after Bernie Sanders’s first presidential run, intraleft debates about whether to engage with the Democrats are largely settled. That campaign taught US socialists much about how — and how not — to build a powerful socialist movement.

Ten years ago, while socialist Bernie Sanders was making his historic run for the Democratic presidential nomination that drew millions of supporters and promised a “political revolution” to live long past his campaign, I was part of a small revolutionary organization that pooh-poohed him as a faux renegade.

The socialist left at the time had been largely marginal to the American political landscape. This was not only because so few socialists sat in political offices.
