Note: Roslin states that the chair will remain open for nominations for 72 hours on the morning of Day 47, but the next episode clearly takes place the day after the victory party, and is stated to take place on Day 50. Perhaps the Quorum moved to close the nomination period early after the nomination of a strong candidate.
