The title applies to the relationship of a potential Republican nomination (Spencer Tracy) to 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 be suggesting that her character is the more natural leader. Lansbury is wonderfully chilling as a manipulative agent of the far right.
This was Frank Capra's last masterpiece, though it was a departure. It's quite naturalistic compared with his great political fantasies of the thirties. Only at the end when Matthews confesses to his dishonesty on network tv and calls for labour and capital to pull together do we feel the director's 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 cynical vérité. It feels true, and it feels it is still true.
