The title applies to the relationship of a potential Republican nomination (Spencer Tracy) with his wife (Katherine Hepburn). And of course, to the condition of the United States. The marriage is threatened by a predatory young press magnate (Angela Lansbury) while democracy is vulnerable to powerful vested interest.
It's an exposé of Washington realpolitik and the parasites and henchmen that attach themselves to the public relations roadshow. Tracy is persuasive in the lead. Hepburn has a support role though the film seems to suggest that her character is the more natural leader. Lansbury is wonderfully chilling as a manipulative agent of the far right.
This is Frank Capra's last masterpiece, though it is a departure; more naturalistic than with his great political fantasies of the '30s. Only at the end when the candidate confesses to his dishonesty on network tv and calls for labour and capital to pull together do we feel the old touch.
We witness a political machinery which promotes narcissism and rewards insincerity. This is a comedy in the sense that the people who occupy the screen talk with in constant flow of irony, which evades explicit meaning. The writing is sharp and witty, but the strength of the film is its believable cynicism. It feels true, and it feels it is still true.
