It's election season, and so once again people look for heroes. Is Ron Paul one? Maybe. He's fought a long, lonely battle to limit the power of government. "As government grows," writes John Stossel, "I yearn for champions of freedom who fight back. Rep. Paul has done that. But it's a mistake to look for heroes in politics. It's too ugly a business. My heroes are people like Milton Friedman, F.A. Hayek and Ayn Rand, and others."
