American conservatives grapple with Cdn election

...and ask: Why don’t Canadian conservatives support Quebec secession?

Law professor Ilya Somin writes:

"Quebec is the most statist province in the country and its political influence drives Canada’s economic policies well to the left of where they would be in a separate anglophone Canada. Canadian Conservatives hate paying for federal government subsidies to Quebec (Quebec is a major net recipient of transfer payments from the federal government). Obviously, there would be no such subsidies if Quebec were an independent nation..."

Hmm? Why did Americans bother fighting a Civil War? Why not just let the South secede -- afterall, they disagreed about slavery.
