Canada PM suggests he might call an early election

Canadian Prime Minister Stephen Harper said Tuesday he might call an early election, a move that would head off opposition efforts to topple his minority government. Harper's Conservatives have a tenuous hold on power, and all three opposition parties have said or suggested they will try to bring his government down with a no confidence vote soon. Harper seems bent on having the election now, with analysts saying his chances of winning are greater sooner than later. To do so, however, Harper will have to maneuver around a law he helped enact after he came to power in 2006, a law that sets a fixed date for an election in October 2009.
