From Lady Di to Michelle Obama

That same week, in the midst of the worst economic crisis since the 1930's, a national poll found that support for President Barack Obama was remarkably high, with respondents consistently saying that he "cares about people like me."

These two phenomena are closely related. Almost from her first appearance in the public eye, Michelle Obama has used clothing, etiquette, and such cues as where she shops and entertains to send out a subtle but radical message to American voters and to the world. For the first time since the days of Andrew Jackson, the White House is aggressively "democratising" the highest office in the land, and symbolically inviting in the common man - and now the common woman.
