Hillary Clinton is expected to secure her party's presidential nomination at the Democratic National Convention (DNC) on Tuesday night, during a roll call vote that the Associated Press predicts will be an "emotional coda for Bernie Sanders supporters whose passion and energy took the Vermont senator from fringe candidate to serious contender."
All of the energy and angst of the hard-fought primary battle between Clinton and Sanders will culminate in the roll call of the states. Each state delegation will get a chance to announce how its delegates are voting. Sanders delegates have pushed to have their votes fully tallied.
Sanders has left open the possibility that Clinton could receive the nomination by acclamation—or unanimous nomination—at the end of the roll call. That may not satisfy his delegates. Some are ready to boo or even walk out if there is a unanimous nomination.
In 2008, Clinton halted the roll call midway through to call for then-Sen. Barack Obama's approval by acclamation, or unanimous vote.
Sanders himself may make an appearance:
Jeff Weaver tells @SteveKornacki that Bernie Sanders will "potentially" appear and speak tonight during roll call.
