Hillary has many extreme makeovers. My guess is that she has maxed out on the botox treatments and has decided that the more natural, mature look, radiates a more powerful appearance. Plus, it would be impossible to maintain until 2008 and she doesn't want to look like Nancy Pelosi.
I wnder if any photos exist of Hillary's mother. That would give us some idea of her true 59-year old face. Some people age withour wrinkles, some have faces that sag like Helen Thomas. I'm thinking that Hillary's genes are in the latter category.
