The worst part, aside from the cat-fighting, is that Fiorina recently underwent chemo for breast cancer, so we can't make fun of her hair. Otherwise you totally would! She probably knew this and intentionally dropped the comment on the open mic (See: West Wing) in order to make Babs look old and to play the cancer card. I said it! Anyway, here is an examination of Senator Boxer's hair, which is really not that bad.
the natural grey
the bob (maybe not her BEST look)
Ehhh sleek is not really that great a hair choice unless you're Twiggy.
