Preferences: Lets see:
My vote goes to the right Honorable Stephen Harper because, in my opinion, the other leaders are not ready to represent Canada on the global stage.
(and NO, that's not the only reason, as I realize to expound my argument fully would require a Ph.D Dissertation)
I don't think anyone knows the politicians running (at least not on a personal level)...But they know their names and their respective parties...And if they had some more brains (I hope they do) they would look into what policies/ideologies those parties stand for.
Yes, I care (and so should YOU) because this is democracy at work.
You can vote for what ever party you wish, it is YOUR right.

I can only comment that you should seriously think before you decide...
