I'm always in favor of seeing a Liberal anywhere defeated but the reality is that this will make no difference in relations between Canada and the US. Candaians as a whole have decided to take the European approach. Weakness is good, the ability to defend yourself militarily is bad, socialism and the ensuing inevitable poverty is good. When things go bad just blame America and George Bush as a one size fits all excuse.
Such a shame.
Most of those voters are not voting Conservative though. In Quebec (where anti-Americans are in the majority), they are voting Bloc en masse. Outside of Quebec (where they are in a sizable minority), they will either be sticking to the Fiberals, but more likely voting NDP or staying home.
