The Washington Post tries to contact more than 1,400 Tea Party organizations. Only a minority, 647, bothered responding. Of those who didn't hate the Post enough to ignore the call, 66% percent reported media coverage of the Tea Party was at least "somewhat fair." That works out to about 420.
The Post' spin based on the fact only about 420 of more than 1,400 Tea Party organizations said the media were at least "somewhat fair?" That the Tea Party doesn't believe in media bias.
Of course, this is the same paper who polled Virginia voters, found less than one percent cared about Bob McDonnell's college thesis paper, and wrote a hysterical front page story that Virginia voters were concerned about McDonnell's college thesis.
