On the eve of Ellie's (recurring guest star Nina Siemaszko) White House wedding, a military situation in Central Asia takes Bartlet away from the rehearsal festivities. Meanwhile, the election is 6 weeks away, and Santos is trailing by 7 points. Josh, Leo and Santos strategize over where to spend their rapidly dwindling monetary resources. Some Democratic Party loyalists want Santos to replace Josh, but Leo advises against it. And Bartlet takes a break from being President to walk his daughter down the aisle.
