"The West Wing" cast is back together, walking and talking, but it's not for a movie.

The cast of Aaron Sorkin's NBC political drama reunited in support of Bridget Mary McCormack, the sister of series star Mary McCormack, who is running for the Michigan Supreme Court. In the video, the cast discusses why it's important to remember to vote in the nonpartisan part of the ballot. The cast reprises their famous "West Wing" roles, including Martin Sheen playing the president once again.

Series star Josh Malina, who can now be seen on "Scandal," tweeted photos from the set of the political ad and teased it as a "West Wing" movie.

This isn't the first "West Wing" reunion of 2012. The cast previously reunited for a Funny or Die video to promote walking.
