During his national tour, Senator Bernie Sanders draws a large crowd in Omaha to discuss solutions for working families and challenges posed by oligarchy.

The senator worries that too many Democrats remain reluctant to shake up the system. But he does not regret defending Joseph R. Biden Jr. until the very end.

Sen. Bernie Sanders drew a lot of support Friday night at his "Fight the Oligarchy" town hall in Omaha. He said he didn't come to change Nebraska politics, but to get citizens to put pressure on Omaha's Republican congressman.
