Cunliffe was getting nowhere slowly. Wisely, he changed tack completely to coat-tailing, asking Key if he was still considering doing a "shady deal" with Colin Craig's Conservative Party when four-out-of-five voters were opposed to such arrangements.
But Key threw the question back at Cunliffe. Would the latter rule out a deal with Internet-Mana, given that party would be seeking to bring MPs into Parliament on Hone Harawira's coat-tails?
Cunliffe countered by saying if Labour ruled out a deal with the Internet-Mana Party, would National rule out deals with the Conservatives, Act and United Future?
Key ducked the challenge. He had to. National has no choice but to embrace such deals to bolster its chances of remaining in power.
The Prime Minister instead turned his blowtorch on the Greens, accusing that party of talking mumbo-jumbo on the fate of the Maui's dolphin and damning Labour for seemingly backing the Greens' opposition to his Government's decision to tender for oil exploration permits in the West Coast North Island marine mammal sanctuary.
By late afternoon, Cunliffe had once more indulged in political acrobatics by trying to clarify Labour's position and somehow satisfy both environmentalists and the oil industry.
