In the political comic Doonesbury, President George W. Bush was symbolized by a Stetson hat atop a giant asterisk. The hat referred to his time spent as Governor of Texas; Doonesbury artist Garry Trudeau refers to Bush of being "all hat and no cattle".<2> The asterisk was intended to represent the special circumstances surrounding Bush's election, it being the typical symbol to mark footnoted special circumstances in any standard record book.

Later, President Bush's symbol was changed to a Roman military helmet (again, atop an asterisk) representing imperialism. Towards the end of his first term, the helmet became battered, with the giltwork starting to come off and with clumps of bristles missing from the top, but on September 2, 2006, he fantasized about himself wearing a crown.

More recently, personal symbols reflecting some aspect of their character are used. For example, members of the Bush family have been depicted as invisible. During his term as Vice President George H.W. Bush was first depicted as completely invisible, his words emanating from a little “spark” in the air. This was originally a reference to the man’s perceived low profile and his denials of knowledge of the Iran-Contra Affair. (In one strip, published 20 March 1988, the vice president almost materialized, but only made it to an outline before reverting to invisibility.) President George W. Bush was later symbolized by a Stetson hat atop a giant asterisk (a la Roger Maris), because he was Governor of Texas prior to his presidency (Trudeau accused him of being “all hat and no cattle” ) and also due to the controversy surrounding the 2000 presidential elections. Later, President Bush’s symbol was changed to a Roman military helmet (again, atop an asterisk) representing imperialism. Towards the end of his first term, the helmet became battered, with the giltwork starting to come off and with clumps of bristles missing from the top. (By now, the helmet has been dented almost beyond recognition.) On 2 September, 2006, he fantasized about himself wearing a crown.
