With Ignatieff as leader:
Con. 38%, Lib. 24%, NDP 18%, BQ 11%, Grn. 8%
With Rae as leader:
Con. 39%, Lib. 21%, NDP 19%, BQ 12%, Grn. 8%
Ignatieff does slightly better, although within the margin of error.
On the question of voter preference, Ignatieff enjoys a wide lead amongst past Liberal voters, as well as the general public:
Among Liberal Party voters:
Ignatieff 35%, Rae 25%, LeBlanc 6%, Not sure 35%
If Canadians could pick leader:
Ignatieff 23%, Rae 17%, LeBlanc 8%, Not sure 52%
I find the Liberal voter numbers somewhat striking. Maybe more curious, you would think if Ignatieff bests Rae with all voters, the Ontario subset would be part of the story. However the two are tied with 21% respectively for preference in Ontario, Ignatieff actually gains his edge elsewhere. In Quebec, Ignatieff is preferred by 31%, Rae only 11%, something to chew on. Also, amongst BQ voters, Ignatieff stands at 32%, Rae at 11%. In fact, Rae only bests Ignatieff in Alberta.
When voters are asked their party preference, we see that with Ignatieff at the helm the Liberals enjoy 6% more support in Quebec, than they do with Rae. Ignatieff also does better in Atlantic Canada and British Columbia, while again, in Ontario no difference between the two.
One of the arguments for an Ignatieff candidacy, he has the potential to improve Liberal fortunes in crucial Quebec. These findings tend to support that, or at least suggest a positive starting position. The other part of this poll that I find relevant, the Liberal voter gap is considerable, Ignatieff has a clear lead, with the only caveat, a sizable "not sure" percentage.
