Oh good grief, someone show the swan picture will ya 'cause I can't find it.
I do, however, agree with Anna that male politicians are also subject to this king of image analysis. I remember seeing one on Bill Clinton's changing hair colour when he was running for president. It would change from brown to grey to make him look older or younger depending on wh ohis audience was on the campaign trail. And, JFK's looks have certainly been given much credit for his success.
In fact, I think politics is one of the very few professions where a man's appearance does matter as much as a woman's.
