I'll come across as Hamiltonian here instead of Jacksonian, but never underestimate the stupidity/ignorance of people in elections or referendums.
My opinion of the DPP is similar to my opinion of the BQ (full of tribal little people that have very little knowledge of economics and who couldn't run a peanut stand ).
Quebec, considering how much power it has relative to its population within Confederation and how it is subsidized big time by the wealthier provinces, would be absolutely crazy to leave Canada. It has it so good when it comes to the largesse it receives from the Feds, to the representation it gets in parliament and the civil service, and to the economic subsidies it receives in equalization payments or other goodies. It would be crazy to give all this away to become a third-world entity. They would be crazy to leave.
Similarly, Taiwan, which already in practical terms is independent, would be absolutely crazy to risk its economic standing by provoking Beijing with the pipe dream of independence.
Fuck the dreamers on this one! Do I support the right to a referendum? Sure. Do I think they'd do the smart thing? Probably not (although I think the Quebecers now realize the economic implications of going it alone).
