Regular Doonesbury readers will recognize that Gary Trudeau never tries to draw major political actors, choosing instead to represent them with an icon that captures their core characteristic.
Dan Quayle was a quail feather (seeing as he was an intellectual featherweight), Bill Clinton was a waffle, Bush Jr has been a Roman helmet, getting more battered with every new disaster (I forget what poppy Bush was).
So - how will Gary Trudeau represent Barack Obama? A halo? A pair of Messiah slippers? Cool-jazz shades? Put in your suggestions - keep it simple - maybe Trudeau will read this!
