The prodigious Penn, a pollster and counselor to the Clintons since 1995, has risen to the commanding heights of the public relations and research business over the three decades since he entered politics. Having started in a tiny, two-man polling operation in a New York City mayoral campaign, he is now the CEO of Burson-Marsteller Inc., one of the planet's largest P.R. shops, with corporate clients ranging from Microsoft to Shell Oil and Pfizer. For progressive voters, those connections should raise questions about Penn's dominant role in the Clinton campaign, especially because he has reportedly boasted about the business benefits of his political power.

So here was a conflict of interest that seemed both direct and salient. Sen. Clinton is a declared supporter of labor rights who often tells workers that she is on their side. Besides, she badly wants the support of the Teamsters and UNITE HERE, the unions seeking to organize the Cintas employees, not to mention all the other labor organizations that might help her win the nomination and the presidency. But on the issue of workers rights, her top advisor has been on the other side.
Or has he? Penn said that he had nothing to do with the Cintas account, even though he is Burson's CEO. Moreover, he took offense at the implication that he might be anti-union. He recalled that his father had helped to organize the poultry workers union in Queens, N.Y., where he grew up. Unsurprisingly, his indignation and sentimentality did little to persuade union officials of his sincerity. They know very well that Penn is among the leading figures in the Democratic Leadership Council, whose budget is underwritten by major corporations and whose policies favor business over labor. Even the lunchboxes at DLC conferences display corporate logos.
