Tara has a great post taking Adam Graham to task for his Ad Hominem attacks on her and MG.
Adam's pace of blogging demands much material but doesn't seem to allow time for much research or spell checking. He tends to pile onto what ever the R reactionary wing is griping about at the moment, and doesn't hesitate to make personal comments. They're not as mean as they could be, and not as mean as many leveled at him, but still, he does tend to attack the messenger in an effort to discredit the message. Standard winger tactic.
And no, I'm not putting up any examples. Read his site; examples abound. Tara cites a few in her post.
