"Stephen Harper, who's the prime minister of Canada, he is saying that this - we have to give him a majority government, otherwise there will be a Separatist coalition. And he says it every minute"

Rick Mercer is referring to Stephen Harper, the Prime Minister of Canada, and his stance on the requirement for a bulk government. Harper thinks that if a bulk government is not accomplished, a Separatist union will form. This is a reference to the separatist movement in Quebec, which seeks to separate the province from the rest of Canada. Harper has been vocal about his stance on the issue, and Mercer is suggesting that Harper is repeating his message constantly. This quote is a commentary on Harper's persistence on the requirement for a bulk federal government, and the possible effects of not achieving one. It likewise works as a tip of the importance of the upcoming election, and the prospective ramifications of the result.
