Question for the Politically Adept: What Constitutes as a "landslide" in US Presidential Elections?

Since the question has basically been answered that a large majority of electoral college votes (+176 for Obama) and popular votes (+7,558,695 for Obama), I would say that this constitutes a landslide. North Carolina, Missouri, and Indiana have yet to be decided, so it could get worse. Seriously, it wasn't really close regardless of what the political pundits (Fox) say. It is a mandate that the Republican ideology is not working for America right now. Get used to saying 'President Obama' for 8 years, America.
