I will add one thing wrt the last line about Wikipedia entry. The editing log for Palin's Wikipedia entry notes that someone went through shortly before the announcement and made major changes.
McCain doesn't remember how many houses he owns. Palin can't remember how many children she had?
Interesting that she is in favor of contraception but not abortion. Apparently neglected to pass that piece of advice forward.
Update Color me stupid for being taken in by an excellent parody. Still, the Wikipedia thing is interesting. I await the authentic Palin at the RNC with great interest.
