A couple of posts ago, I was asked in a comment by one of my regular castigators which of the candidates I felt were "the strongest allies/foes of corporatism". I felt that was a fair question, and one which deserved careful consideration. After due deliberation, I'm ready to answer. Much of the following biological and funding information comes from Project Vote Smart, which has a fairly nice site with easy links to the information regarding the remaining active candidates. With a bit more effort, one can also locate all of the others.
I'll get to my foes of corporatism first, as that list is very short: Dennis Kucinich and Mike Gravel. Each is essentially running on one and the same issue: ending the war in Iraq. I feel that this lack of a broader appeal makes it easy for both to be marginalized as they are by the media, the best measure I can use to demonstrate that they aren't corporate insiders.
I know that Ron Paul has had his troubles with the media as well, but he's been included in debates through the exertion of less effort than Kucinich, who remains excluded despite the exertion of far more effort.
As for the allies of corporatism, just look at all of the other candidates of both parties. You have corporate lawyers (Clinton, Obama, Edwards, Biden, Dodd), corporate executives (Romney), corporate lackeys (Hunter, Thompson), corporate shills (Keyes, Tancredo), corporate crooks (McCain [see: Lincoln Savings]), corporate televangelist (Huckabee), a corporate clown cross-dresser (Giuliani), and sitting corporate governance servants (Paul, Richardson).
Then see where their campaign funds come from, courtesy of Open Secrets. The following figures are the percentage of total contributions which came from business interests:
