It's a Joke, Son! (1947)

Claghorn gets into some financial difficulties and is forced by a machine-political gang to enter a race for state senator against his wife (Una Merkel) who appears to have a good chance to beat the political hack backed by the machine. Claghorn is in to siphon votes and ensure his wife's opponent will win and is expected to run a campaign that will defeat himself and his wife. But, he runs to win and the machine's henchies abduct him.
