The thing about Scott Walker, the Wisconsin governor who just "suspended" his campaign to become president of the United States, is that he was a not-very-appealing candidate who didn't appeal to many people. But sour pusses usually don't. When it was reported recently that the Koch brothers demanded their $900 million back from Walker after he conceded to Republican voters that no one really likes him, there was broad agreement that this spat over cash couldn't happen to a nicer group of people.
