Now I know ...

What it is about Romney that puckers my sphincter so badly. Perfesser Krugman hit's it:

...

The point isn’t necessarily that Romney has lived in privilege all his life; so did FDR. It’s his apparent inability or unwillingness to imagine what it’s like for those less privileged, his complete failure to try, even in his imagination, walking in someone else’s shoes that stands out.

Exactly.
