The night before the United States presidential election, the Steelers played in the nation's capitol, Washington, D.C.; both major party candidates were interviewed at half-time. The Washington Redskins took a 6-0 lead in the first quarter with two field goals. The Steelers defense shut out the Redskins in the second quarter while the Steelers scored on a field goal to cut the lead in half. A blocked punt with 2:21 remaining in the half led to a Steelers 1-yard touchdown run from Ben Roethlisberger. Due to an injury to Roethlisberger, Byron Leftwich took over as quarterback in the second half. Leftwich completed a 50-yard pass to Nate Washington on the opening drive of the third quarter; the Steelers capped the drive with a Willie Parker touchdown run. Pittsburgh extended their lead in the final quarter with a touchdown pass from Leftwich to Santonio Holmes. The Redskins gained 124&#160;yards in the final quarter, but were unable to score. The Steelers' 17&#160;point win took their record to 6-2 on the season.
