Tracy, the actor, had never manufactured even a hairpin, yet mentally, physically, and psychologically he was the very rich American industrialist who wanted to put his know-how and ideals about democracy into the service of better government. And Hepburn, the actress, was the very-much-in-love wife who saw the ideals and hopes of her strong, decent, patriotic husband being twisted, warped, and compromised into cheap vote-getting tricks by a gang of hungry politicos too long away from the patronage trough. — FC
