I wouldn’t mind seeing the Libertarians get about 10% of the vote, not because I agree with their platform but more as a wakeup for the mainstream parties, and to nudge them a little further right. This would only take votes from the Conservatives so I guess is not really desirable in a tight election, I don’t think the Cons could ever get a large enough lead over the Liberals that they could afford it.
Libertarian government ? Not a chance.
