Washington (CNN) -- Ralph Nader floated the idea this week that a primary challenge to President Obama will help the president and the country. He is flat-out wrong. His views are based on a faulty premise and a myth. We will start with the faulty premise and get to the myth later. Remember back to 2000, when Nader himself ran as a third-party candidate? He's not proposing that here -- at least not yet -- but it's important to remember what happens when Nader gets involved in challenging a Democrat. In 2000, he siphoned enough votes from Al Gore in Florida to swing the election to President Bush. It gave us eight years of Bush-Cheney politics and policies.
