By Rachel Alexander, The Stream - Thanks to his billions, former New York City Mayor Michael Bloomberg is getting some traction in the Democratic presidential race. But as he becomes more visible, so does his past. He’s given his opponents good reason to dig up dirt on him… And boy is there a lot of dirt… Not even farmers are safe from Bloomberg’s contempt. He belittled them four years ago on a panel at Oxford University. “I could teach anybody, even people in this room, no offense intended, to be a farmer…It’s a process. You dig a hole, you put a seed in, you put dirt on top, add water, up comes the corn. You could learn that.”
