Perhaps the best example of a sociopath (Newt Gingrich video) have ever seen
 

Here we have a soulless career politician getting a totally staged question in a well rehearsed bit. He even tells you he is "going to get teary eyed" before he actually manages to make himself tear up a little bit. The the people who buy into into these crocodile tears should not be allowed to even vote. The interviewer/political pollster (Frank Luntz) has got to be having a laugh watching these gullible Iowa simpletons give sympathy to this lizard.
