The general consesus among the punditry is that these Harris-Decima numbers are way off, that the Tories are not up 15 points over the Liberals. I suspect, though, these may turn out to be rather prophetic numbers.
Dion has been defined by the Tories. The public truly does see him as a wimp.
Ignatief might have won this election. Rae would have been creamed, tarred, sometimes unfairly, with all the crap the Tories could dig up from Rae's term in office. He would have got the last laugh, though, since there's no way the Harper "team" has the depth needed to handle this recession.
The election of 2012 will put the Liberals back in power. In some ways, they should be glad they're losing.
As for an NDP-Liberal coalition, the only way that can happen is if the Dippers and Liberals hold all the seats they have and the Bloc loses seats only to the Liberals or NDP, or if the Tories lose a whack of seats to the NDP. Otherwise, it's mathematically impossible. The tories won't lose seats in this election, and if the Bloc does lose some seats, it won't be to Dion and Layton.
