What's with powerful women and thick bumpers of bangs?

Drudge is — I think — implicitly asking with this alignment of photographs:



What drives intelligent women to that hairstyle? Are they thinking something like I don't want those feathery bangs...



... or the classic Louise Brooks straight-across look...



... but I can't have my forehead just out there to be gazed at!



What's wrong with foreheads? Is it that the forehead symbolizes the mind, and a woman can't have you looking straight at that? The intelligence must be filtered. There must be a buffer zone of femininity, so there must be some hair veiling the forehead — the theory seems to be. But why the bumper look that we see in the Drudge trio of Angela Merkel, Condoleezza Rice, and Maureen Dowd?
