Robert Kennedy Jr has made a career out of saying stupid things, such as his argument earlier this year that hog producers posed a greater threat to this nation than Osama bin Laden. However, his latest attack of foot-in-mouth disease will probably cost him a lot more dearly, or at least it would, if the Left had any sense of consistency. Kennedy called Barack Obama an “indentured servant” to the coal industry: “Clean coal is a dirty lie,” says environmentalist Robert F. Kennedy Jr., who calls President Barack Obama and other politicians who commit taxpayer money to develop it “indentured servants” of the coal industry. Despite a series of expensive false starts and failures, President Obama proposed $3.4 billion in stimulus legislation to fund continued research on “clean coal” projects. “Clean coal is like healthy cigarettes, it does not exist,” says former Vice President Al Gore.
