Look at pictures, and be honest. But isn't Fred Thompson different somehow? Isn't he "good bald"? Or is it just that I'm used to seeing him bald and shocked at the revelation of how Clinton and Reagan would look? Perhaps Thompson's face is so elaborately creased with character that the blank dome provides needed balance. Hair would seem fussy.
Yet maybe we're moving into a time when a shaved-down scalp will look best on a man and the politician's hair we've been seeing for the last quarter-century will look absurdly wig-like and repellent.
But to look good bald, you need a well-shaped head. One reason Reagan and Clinton look so stupid in the caricatures at the link is because the artist has given each of them a narrowing cranium, a pointy ridge of a head. Compare Thompson's head: high, big and rounded. It may be that Reagan and Clinton had similarly well-shaped heads.
Come to think of it, wouldn't you like to get a look at a man's head before electing him President?
This last question has me off and searching for a picture of Zippy the Pinhead. A cool thing about the Zippy website is this page with a clickable map of the United States, which lets you find old strips set in whatever state you want. Zippy, not being a presidential candidate, has not yet visited Iowa. But here's a strip from Wisconsin. Interestingly, the last panel may give a clue what it is we fear about the bald head.
