It's worth remembering, as we enter the culmination of a very loud Internet election season, that out there in the real world, only 8% of voters claim to be voting for one because they "dislike" the other (10% say that while voting for McCain, 6% for Obama).
(Check that methodology so you know what that means. It's a free form answer question. If the question were asked as "Which of the following statements do you agree with?" it would be a different result. But I think that this is revealing in its own way.)
I'm sure "hate" would be an even smaller response.
The media... and I include the internet media here too... the media as a whole delights in bringing you the story of extremes. But the extremes are... extremes.
