Which ones specifically are lies? Some of those quotes from Harper are things he's actually said. The one about a US paper saying he's pro-US, I've never heard of it but it's pretty hard to fake something like that.
I'll never understand it. Harper is a right-winger, right? That's been pretty well established. When the Liberals say "Harper is a right-winger" the right-wingers say "they are lying" or "that's just fear-mongering".
