Like Reform, Polanski’s team has so far tried to paint in populist, primary colors.
His first party political broadcast — a convention by which parties are given guaranteed five-minute TV slots — was filmed in the early hours as a metaphor about billionaires sleeping comfortably while others struggle. “Both were efforts to visualize things that you can’t see and to consciously make them as simple as possible,” Clancy says. Those short videos racked up millions of views.
Whether this translates into electoral success, however, remains a wide open question. Next May’s local elections will offer the first real ballot box test of Polanski’s pitch.
Ipsos’ Research Director for Public Affairs Keiran Pedley says the Greens are “still waiting for that breakthrough moment” and now need to “seal the deal” with voters.
He cautioned against assuming cut-through for a leader will lead to electoral success. Pedley compared Polanski to ex-Liberal Democrat Leader Nick Clegg — who lost seats at the 2010 general election despite a major polling bounce mid-campaign off the back of strong televised debate performances.
For now, those who’ve joined the movement seem bullish. “The Greens have gone from being a one-issue party, which is the environment, to basically being the broad left party,” said Swindon Borough Councilor Ian Edwards, who joined the Greens in October after resigning the Labour whip earlier this year.
But he added: “We can’t rely on just a leader. We’ve got to prove ourselves.”
