I may be blanking on it, but I don't remember many conservatives attacking Chelsea this way. I distinctively remember people who attacked her on FR generally getting their heads bit off by other posters.
As they should.
If you thought you knew how petty, tasteless and filled with maniacal vitrol the left was, read this attack piece on the recently engaged Jenna Bush.
You forgot poorly written and boring.
That was my first thought as well.
Sure, Jenna and Barbara had a couple of unflattering media moments when Bush was first elected (for behaving in a fashion that many of us who post here could easily relate to) but, as far as I can tell, they have both kept their noses clean and stayed out of trouble for the last several years.
