The film follows McKay (Robert Redford), a lawyer who embodies the familiar image of an activist representing people in California. He's unexpectedly asked to challenge Senator Crocker (Don Porter), a Republican, in what seems like a formality for the Democratic party. McKay only consents to running if his campaign manager, Marvin (Peter Boyle), allows him considerable freedom to speak and act as he chooses during the election. Soon, his straightforwardness begins connecting with voters grappling with significant social and financial problems, feeling neglected by a senator who has become removed from their concerns due to years in Washington and the Senate. As McKay’s campaign gains momentum, his initially skeptical advisor starts taking things more seriously and attempts to exert control over what was previously an unorganized approach. To achieve victory, it remains to be seen how much he will have to concede or adjust his positions. Redford is well-suited for the role, bringing a sense of realism to political campaigns that often feel like voters are being disregarded. His lack of polish, directness and willingness to consider new ideas are viewed by many as signs of promise and encouragement, which he portrays effectively. The story takes place in the United States during the early 1970s, but its themes could apply to numerous democracies where politicians are elected and routinely re-elected based on party affiliation rather than a commitment to addressing the changing needs of their communities. While it doesn’t necessarily provide groundbreaking insights, the film provides an observant examination of what happens when established systems are challenged. The question remains: can he actually succeed?
