I don't know why she didn't just say she disagreed (or agreed) with "most" of them, or maybe a "vast variety of them."
Tonight's debate is dangerous territory. She been so shockingly bad in these interviews that she has lowered the bar very low, to the point that as long as she doesn't break out the ole "I'll have to get back to you on that one" or fail to remember her running mate's name, she'll probably be lauded as having been successful, no matter what she actually says or fails to say.
The reports of her utter failures in preparatory mock debates only feeds into this game. Let us not forget where this information is coming from (camp: McCain/Palin).
