jdobbin,
You keep basing your entire doomsday prediction on the current "trend", making the assumption that the trend will not change, or even level off. In the last two elections we've seen changes in momentum, so what makes you think it can't happen this time? You know that old saying about a week in politics...especially true during a campaign. There are a number of things happening, or just around the corner that could yet move the numbers:
-increasing financial market turmoil
-release of Afghan mission cost
-the leaders' debates
-the delayed/not delayed proceedings on the "in-and-out scheme" & Cadman
-Julie Couillard's book release
-misc...there is usually something (gaffes, candidate revelations, etc.)
This is not even taking into account Williams' ABC campaign or the 4-on-1 gang-up of attack ads that will ramp up as the election continues.
Indeed, we are already seeing a plateau in the Conservative numbers:
Wikipedia - Opinion polling in the Canadian federal election, 2008
Since the writ dropped on Sep.7, only 2 polls out of 21 put the Conservatives above 40%. All others have them hovering around 36-40%, with the most frequent number at 38%. Nanos, which got the last two elections right, has the gap at 7 or 8 pts over its last 6 samples. If there is an upward trend, it is barely there. Really, I'm seeing a stagnation, just shy of majority territory. Not good numbers for the Libs, but not a collapse to 42 seats as you suggest. Looking at the electoral map, even in an extreme case, I can't see the Libs getting less than 55 seats, nor the Conservatives more than 185 in this election. I don't see the NDP getting 55. No Stornoway for Layton.
I will agree that the Liberals are in trouble financially, but that doesn't mean they'll perform poorly come Oct.14. Anyway, even if the Liberals collapse into the financial abyss afterwards, another centrist party will be formed, because politics, just as nature, hates a vacuum. The party will just have a different name, but have most of the same players. This new party will have to emerge fairly quickly, because Harper and Layton will be moving to fill the space between them. Or maybe it'll be the Greens that grow into that space??
Disclaimer: I am not a Liberal voter.
