According to the new book, The Amateur: Barack Obama in the White House, by Edward Klein, Michelle Obama was so angry in 2000 that her husband had run for a House seat and failed miserably that she prepared divorce papers against him. Obama had taken on Bobby Rush, a four-time incumbent on the South Side of Chicago, and lost by a margin of two to one.
Michelle Obama had warned her husband not to run, but he ignored her advice and ran anyway. After Rush destroyed Obama in the election, he called Obama “an educated fool.” Later, when Michelle Obama prepared the divorce papers, according to friends, her husband became so depressed that he was suicidal. Klein describes the situation at the time this way.
