I know this is going to sound preposterous, but try to imagine a politician who is completely incompetent. An idiot. A total buffoon. That is the story of Sen. Melvin G. Ashton, played by William Powell.
Ashton, planning for a career after being a senator, decides that the only other job he's qualified for is to become president. He seeks the job not just for himself, but for the benefit of all the relatives he has on his payroll. Through the movie, he quickly shows the wisdom he has picked up from his years in office with lines like, "If you can't beat 'em, bribe 'em!"
Ashton commences on a coast-to-coast tour to announce that he is NOT running for president and take some courageous stands on issues ("Ashton is against inflation, against deflation, for flation.") The villainess in the movie is a reporter played by the fetching Ella Raines, who vows to kill Ashton's campaign by quoting him accurately.
For some reason, the party leader doesn't want Ashton to be president. However, Ashton has kept a diary through the years that detail the shenanigans of other politicians and he's ready to use it as blackmail. The only problem is he loses the diary, and then the search is on to find it, by both party people that want to destroy it and others that want to publish it.
The people who will like this movie best are the ones that enjoy light comedies. I absolutely loved it. After seeing it, I'm sure you'll join Steven Colbert in asking, "Melvin G. Ashton: Great senator or greatest senator?"
