Saw that. But I don't think it's a vote getter as presented. It's rather vague and not well fleshed out.
Make it a serious policy proposal rather than a "thinking out loud" idea and you might have something.
I also think it would be a far bigger deal if the idea came from the other two parties. And I wouldn't write off the Conservatives on this one entirely. Personally (and many will disagree with me here), I actually think HSR might just be an idea that sellable to the Conservatives. It's a vote getter in Quebec. A big infrastructure project with a national legacy. And would have a lasting economic long term impact that would seriously harm the sovereignists. I'm sure there's at least some Conservatives who are warm to the idea.
Most of the ridings that it would pass through aren't Conservative ridings. Hence, they wouldn't get the money from it. If it were up to the Neo Cons, we'd have a piecemeal HSR line that only travelled at high speed through Conservative ridings, and at regular speeds everywhere else.
