Because Tory partisans will pick up on this quickly enough anyway, the new Ipsos-Reid poll does not show that the PM's war stance has "split" Canadians, as most of the papers would have you believe (for instance The Ottawa Citizen).
Or at least, this reading masks the underlying message of the poll, which is less comforting to progressives. That is, while 45% supported Harper's position, and 44% decried it as "too pro-Israel", another 11% feel it is not pro-Israel enough. Which means that 56% of Canadians support a stance at least as hard as the one Harper is currently taking.
To me the political calculation Harper will make is to work the 11% on-side by maintaining a hard line or adopting a harder line, rather than "back-track" and lose some of the 45% he has already go in the bag. Therefore, from looking at this one poll at least, I don't see the Tories being harmed by "aligning" Canada's position more closely with that of the United States on this issue.
Mind you, 62% of Quebecers see the government position as being too pro-Israel, so Harper has been setting up obstacles in his own quest to win more seats in that province. Its very hard to see his path to a majority by this route anymore, especially since the fiscal imbalance fix is going to amount to much less than advertised.
