The worst thing is, I don't believe she's in mourning for Casey, as much as she is glad to have a reason to be "relevant" (and I use that term loosely) so she can spout her hate rhetoric against President Bush. The only reason she ever mentions her son, who was truly an American hero, is just so she can try to imply that she should have free reign to say whatever it is she wants because she lost her son.

Totally agree. I'll bet her "cause" was Casey, Casey's welfare, maybe to support Casey, and Casey, Casey, Casey. So when the poor lad died, she didn't have anything to cling to (I'm guessing the marriage wasn't too hot at that point anyway). Now she's found something new to cling to, she's all wrapped up in it. In other words, she's a nutcase.
