The left (IMHO) sees the right as having lost touch with reality (e.g. Sarah Palin), or as closeted racists. The right (in my experience) sees the left as weak, mewling followers of a Socialist secret Muslim bent on taking away their guns, making their children gay, and generally destroying 'merica.
I used to live in Central Pennsylvania and have a number of Facebook friends from the region. I saw a large number of 'closeted racists' came out of that closet in the 24 hours before and after the election was called - not my conservative friends, so much as their conservative friends.
The stereotypical liberal as seen by the stereotypical conservative, however, is a complete fantasy - in line with the fantasy that Romney had a chance of winning the election.
Plenty of people on all sides think that the other side is evil. I haven't read more than the one-word titles of Ann Coulter's books to know that she doesn't think that liberals are merely "mistaken".
