It really does matter. In the last Provincial election in Ontario, I voted for the (social democrat) New Democratic Party. They came in a powerful third in what you guys, for some reason, call a "hung parliament" ... I prefer "minority government" .... The party I support, got concessions from the ruling Liberals in return for their support in getting the budget through. Now, the super rich will be subject to a super tax. Something that Ontarians have demonstrated that they want, and something that the parties of the right and centre have been unwilling to do. So in this case my vote did make a difference. It mattered.
