People are making too much of this IMO. Krauthammer stated his erroneous views on O'Donnell but he is likely to write some good editorials in the future. I read editorials from people from all parts of the political spectrum. I am not obligated to agree or disagree with anything but weigh the arguments on their merits. I tend to agree with David Limbaugh more than anyone else but I won't quit reading anyone just because I disagree with him or her.
To what "erroneous views" are you referring?
