On a separarte note, I don't think the Palin clothing thing is a big deal (the money apparently may include clothing for her family as well). I mean, it's politically damaging, sure, but I don't think it should be. Politicians appear in public, and the clothing they wear is a legitimate business expense, though the price is impolitic.
It's the scale of it that boggles me. I mean, I like buying clothes; there was a while there when I bought myself a cute outfit every week. Even so, I doubt my clothing expenditures in 2007 averaged over $30 per week or so during peak shopping season.
Now, I buy cheap; you
can't do that as a public speaker, so it's understandable that she'd go more expensive. However I went bridesmaid dress shopping with my sister, and the result was somewhere around $200 - $300.
As for Palin's family, the expenses for the family are actually pretty well laid out ($4902 for her husband; $196 for the baby, etc
source). So...the $150,000 is mostly Palin. Understandably you need a different outfit every day of the month. That's still about $5,000 per outfit; 20x the cost of my sister's bridesmaid dress, on average.
