Interesting shift in the NANOS poll on leadership, unlike the Ipsos poll last week, the gains Ignatieff makes on the "best PM" score don't come at the expense of Harper, but from erosion in the other leaders score:
Harper has maintained, even a uptick in Western Canada, while Ignatieff doubles the score of his predecessor, at the expense of Layton, Duceppe and May. The Ipsos poll showed Harper dropping 7 points against Ignatieff, although it also showed him gaining as the expense of other leaders.
The NANOS polls seems to suggest something of a consolidation around Ignatieff as the alternative. Dion considered so weak, people looked to other opposition leaders, to fill the void, they didn't like Harper, but they had little faith in the Liberal leader. Harper's advantage is still large, but not particularly striking in a historical sense, for a sitting PM. Ignatieff is in the game, and that's the realistic expectation.
