The National Review front page link to this article asks:
"Is there a connection between the criticisms of vice-presidential hopeful Sarah Palin and repressed post-abortion grief?"
Let me think long and hard about this one:
This has been another edition of 'Simple Answers To Stupid Questions' (TM Atrios).
The slightly more complicated answer: given all the obvious reasons to criticize Sarah Palin, why on earth would anyone feel the need to reach for something as exotic and far-fetched as repressed post-abortion grief? It's like asking: Why do people dislike George W. Bush? Could it be an unconscious feeling of empathy with scrubby plants and brush?
