In a room full of 450 far-left activists, a leader with the Freedom Road Socialist Organization kicks off a chant: “Protest is a right—not just for the rich and white.”

“Have you heard that the Democratic National Convention is coming to Chicago?” Joe Iosbaker asks the crowd. “Are we going to let ’em come here without a protest? This is Chicago, goddamn it—we’ve got to give them a 1968 kind of welcome.”

In 1968, the Democratic Convention in Chicago was a bloodbath, with 600 arrests in one street battle that was broadcast all over the world. And the group that met here last Saturday, in the local headquarters of the Teamsters Union, wants to repeat history when Joe Biden is named the presidential nominee at the DNC this August. They oppose the president they call “Genocide Joe” for backing Israel in its war against Hamas.
