In 1968, violence at the Democratic National Convention in Chicago, with hundreds of protesters arrested in a police crackdown, upended the party's gathering and soured public opinion in the final months before the presidential election. Now, more than 50 years later, as college campuses across the United States have erupted into protests over the Israel-Hamas war, some experts say history could repeat itself at this year's DNC convention -- also in Chicago. While the 1968 protests were against the Vietnam War, activists today are blaming President Joe Biden for his support of Israel's military operations in Gaza -- and some have expressed intentions to disrupt the party's plan to nominate him this summer for a second term.
