Begin in farm country, late last summer, no particular day. Carmi, Illinois—a town on the Little Wabash River, down in the southern tip of the state, twenty-five miles from Kentucky, population about fifty-five hundred. A group of twelve farmers—burly white men with ruddy complexions and very short hair—sitting around a rectangle of pushed-together tables in a nondescript room, talking with their junior senator, Barack Obama. It was long before Obama decided to run for President, and he wasn’t in a rush. He sat at one end of the tables, leaning back in his chair, his knee propped against the table edge. He wore a tie but had removed his jacket and rolled up his shirtsleeves. A young farmer complained about the Jones Act, a 1920 law that he felt was partly responsible for a detrimental consolidation in the barge market. Another farmer had a question about ethanol.

“My question first arose in my mind during the State of the Union address,” the farmer said. “President Bush said I’m all for biofuels, and then he started talking about switchgrass. And I’m, like, now wait a minute, we’ve got a system where we can make ethanol out of corn. I guess cellulosic ethanol”—which can be made from switchgrass—“is more efficient. But we don’t know how to do it, and we don’t know if farmers are ever going to grow switchgrass, and we don’t know if we would even want to grow switchgrass, so why so much emphasis on cellulosic ethanol?”

“Well, I’m not a scientist,” Obama said, in a leisurely way, “so I gotta be careful when I start getting into this stuff that I don’t wade too deep and then can’t get back to shore. Right now cellulosic ethanol is potentially eight times more energy-efficient than corn-based ethanol, because you eliminate the middle step of converting it into sugar before you convert it into ethanol. That’s my understanding. I know you’re attached to corn, but if somebody came to you and said, you know what, if you take half your fields and grow switchgrass you’ll make the same amount of money or more, then—”

“Not really,” the farmer interjected. “Because I had a guy come to me before wheat harvest and said do you wanna sell your straw and I said no. I said, ‘Don’t even talk to me, I don’t wanna sell my straw.’ ”

“Now that’s interesting,” Obama said. “Why wouldn’t you want to sell your straw?”

“Organic matter!” the farmer said, triumphantly.

“Well, but if it’s economical to you, if it’s a good business decision, you’ll be interested.”

“If you paid me enough,” the farmer conceded.

“If you were paid enough. Now, you know the economics of it better than I do. So we’ve got to sit down with farmers who are growing the crops and figure out what would make sense. Because, look, I’m not a farmer, and what you just described, I want to keep my straw because it’s important, uh—”

“I thought I was the only person who had this idea,” the farmer broke in, “and then in FarmWeek the guest editorial he said wait a minute, he said what we’re talking about is against everything we’ve preached for the last twenty or thirty years, where we return organic matter to the soil.”

“Exactly,” Obama said in a soothing tone.

“And all of a sudden we’re talking about denuding the ground—”

“Which we shouldn’t do. And so,” he said, returning to the topic, “the way to think about this is not to impose ideas on farmers that aren’t gonna work, by people who don’t farm. But we have to create more efficient ethanol if we want to see a significant growth in the market. The fact of the matter is that Brazilian ethanol is substantially cheaper than U.S. ethanol. Now, George Bush wanted to go ahead and let that come in, and myself and Durbin”—Richard Durbin, Illinois’s senior senator—“said no, we would continue to support the existing tariff so that we can have the development of a homegrown ethanol market. I want to make sure that whatever is being done is utilizing the fact that we’ve got some of the richest soil on earth and the best farmers on earth. But the flip side is that farmers need to be engaged and not just put out a hand and say I’m not interested because I’m used to growing corn and beans.”

There are three things that Democratic political candidates tend to do when talking with constituents: they display an impressive grasp of the minutiae of their constituents’ problems, particularly money problems; they rouse indignation by explaining how those problems are caused by powerful groups getting rich on the backs of ordinary people; and they present well-worked-out policy proposals that, if passed, would solve the problems and put the powerful groups in their place. Obama seldom does any of these things. He tends to underplay his knowledge, acting less informed than he is. He rarely accuses, preferring to talk about problems in the passive voice, as things that are amiss with us rather than as wrongs that have been perpetrated by them. And the solutions he offers generally sound small and local rather than deep-reaching and systemic. Take a recent forum in Las Vegas on health care. Here are Hillary Clinton and Obama speaking about the same subject, preventive care.

“We have to change the way we finance health care, and that’s going to mean taking money away from people who make out really well right now, so this is going to be a big political battle,” Clinton said. “The insurance companies make money by employing a lot of people to try to avoid insuring you and then, if you’re insured, to try to avoid paying for the health care you received.” She stood at the front of the stage, declining an invitation to sit down next to the moderator. She spoke energetically but composedly, conveying the impression that she had spent a great deal of time preparing for the event because it was extremely important to her. “A lot of insurance companies will not pay for someone who’s pre-diabetic or been diagnosed with diabetes to go to a nutritionist to find out how better to feed themselves, or to go to a podiatrist to have their feet checked,” she said. “The insurance companies will tell you this: they don’t want to pay for preventive health care because that’s like lost money because they’re not sure that the patient will still be with them. But if they’re confronted with the doctor saying we’re going to have to amputate the foot they’re stuck with it. That is upside down and backwards!”

Now here is Obama. “We’ve got to put more money in prevention,” he said. “It makes no sense for children to be going to the emergency room for treatable ailments like asthma. Twenty per cent of our patients who have chronic illnesses account for eighty per cent of the costs, so it’s absolutely critical that we invest in managing those with chronic illnesses like diabetes. If we hire a case manager to work with them to insure that they’re taking the proper treatments, then potentially we’re not going to have to spend thirty thousand dollars on a leg amputation.” A young man asked about health care for minorities. “Obesity and diabetes in minority communities are more severe,” Obama said, “so I think we need targeted programs, particularly to children in those communities, to make sure that they’ve got sound nutrition, that they have access to fruits and vegetables and not just Popeyes, and that they have decent spaces to play in instead of being cooped up in the house all day.”
