PHILADELPHIA — Sen. Bernie Sanders will put the Democratic National Convention’s “united together” theme to the test Monday night when he takes the stage in Philadelphia and calls on people not to give up on his “revolution.”

Convention organizers hoped to quell unrest from the pro-Sanders liberal faction of their wing with a speakers list that includes major political luminaries of the Left. The lineup features Sen. Cory Booker, D-N.J., first lady Michelle Obama and Sen. Elizabeth Warren, D-Mass.
