Unless I'm forgetting something, my favorite Election Day TV episode is the MTM episode with the blizzard during coverage of election returns. No, not any of the West Wing episodes (unless, again, I'm forgetting one I liked). Second choice? I did really like the Columbo set on Election Day, with Jackie Cooper as a candidate who kills his campaign manager (although I suspect in real life the fantasies are more common in the other direction, campaign managers who dream of murdering the candidate). Others? I'll take any suggestions.
The best Election Day in a movie is an easy choice: The Candidate. Second best? Maybe The Great McGinty? But the very best Election Day moment in the movies, at least to me -- even better than the last line of The Candidate -- is the point at which they finally decide which headline to use to announce the results of the Kane/Gettys election.
So, Wim With Jim, and Happy Election Day!
