I actually prefer minority governments. The leaders need to co-operate with each other in order to pass legislation. Under a minority government, McGuinty will have a hard time pushing bad bills through the legislature assuming that Hudak and the NDP Leader have brains in their heads and can keep the Liberals in check.
Similarly, a Conservative minority federal government, would have prevented Harper from pushing unpopular bills through Parliament. Unfortunately, when you have Ignatieff as the Liberal leader, that pretty much guaranteed a Conservative majority government.
Also remember that Ontario prefers a balance of power related to the federal government. If the Liberals are running the province, the Conservatives are running the country and vice versa.
