Tom Harkin
Tom Harkin is one of the two US senators from Iowa, and is the chairman of the Senate Committee on Agriculture, Nutrition and Forestry, and holds several other interesting committee assignments. He ran for president in 2000, under a platform of bringing back the New Deal, but could not get any traction. Kind of ironic, since we are back in the new deal era anyway.
During the 2008 election cycle, he managed to raise $8 million in "campaign contributions", about $1.5M of which was from "agribusiness" and also, the health care industry. Interestingly, most of his contributions were from lawyers of one kind or another because he is on some insurance committee. Top five contributors: Herbalife, Monsanto, Goldman Sachs, Texas Pacific corp (a "private equity" fund with investments in Del Monte Foods, Burger King and Harrah's Entertainment) and Cassidy and Associates a lobbying firm who has worked with the FDA and USDA in some capacities.
His poor Republican challenger only raised $58K in the last election. Harkin still has about 2 million left over.
I suppose it's possible that this guy will turn on his generous donors and allow the system to be overhauled, but I have to say, per the above, that his consitutents are used to getting a lot of benefits from the government, so it's not looking particularly promising. The state is small enough, that he could probably win the next several elections with what he has on hand, so he might try it.
However, he probably sees his job as two things: protecting the campaign donors that put him in office, and secondly, bringing back as much federal spending to his state as possible. Note that there is a difference between that and "doing what is in the long term beneficial interest of the citizens of the US".
Perhaps we should write him a friendly email, and see what he says. He only got about $90K from energy companies.
