Based on some new information, I added Clinton White House economic guru Gene Sperling to the list of Obama economic advisers. I'm not going to list every corporate CEO who is an Obama-backer, but I also realized that Warren Buffet definitely qualifies as one of the "prominent finance people who supports Obama," so I added him to that part of the list.
Additionally, I see that Nancy Pfotenahauer appeared on CNN billed as an McCain economic policy adviser, so I updated the McCain list here. As Think Progress showed, she is a pure distilled product of Koch Industries, the secretive oil and chemical company which funds much of the right-wing message machine. Her most prominent role was as VP of Citizens for a Sound Economy, a classic astroturf group funded by Koch. Here's one description of CSE:
Based in Washington, D.C., CSE describes itself as an organization of "grassroots citizens dedicated to free markets and limited government." However, it is commonly known as what Public Relations Quarterly has called a "corporate front group." The publication explained that "the use of such 'front groups' enables corporations to take part in public debates and government hearings behind a cover of community concern [in order to] oppose environmental regulations, and to introduce policies that enhance corporate profitability.
