How is it idiotic to believe that a politician could be lying?
If you don't see that other people can be lying, things can get pretty idiotic. Some of the people involved here don't have very much credibility either: Ron McRae for example, or the person who "proved" that Obama's sister's name was on the COLB posted on line. If you're only out to get Obama and don't see that some people on the same side may not be truthful either, you can come to some bad conclusions.
