The Santos campaign meets up with Rock the Vote and lots of musicians are around for a star-studded episode. Helen gives a lecture to MANA (a National Latina Organization, formerly Mexican American National Association) but her heritage doesn't help her when trying to deliver part of the Santos campaign message. Toby is being pressured by the Attorney General, Blake, to reveal his source and it's affecting his relationship with his kids. He tries a little psychological warfare of his own to get Blake to back down. Toby is also giving Josh campaign advice which includes plans to increase courtship of the Latino vote. Elsewhere on the campaign trail, it's Halloween and Toby's kids and Santos' kids are dressing up for the occasion.

As the polls close, and results are tallied, emotions run high as the campaign teams make last minute calls to secure undecided votes. The heart-breaking news of Leo's death sends shockwaves through the Santos camp and the Bartlet administration. Meanwhile, Vinick disagrees with his campaign team on a number of issues, including their reaction to Leo's death. The long, razor-thin election campaign is finally over and the new President of the United States of America is declared. It's a sad day for all as Bartlet and his current staff, as well as some friends from the past, come together for Leo's funeral. And now President-Elect Matthew Santos must choose a new Vice President. C.J. and Danny enjoy a touching moment, and Charlie offers Donna career advice.
