From where I was sitting, John Kerry's performance at last week's Democratic Convention was the most powerful argument yet offered for voting for Ralph Nader. And the fact that Michael Moore dropped to his knees over the weekend in the company of Bill Maher begging Nader to withdraw only fuels my certainty. Across this year Moore has swiveled from Wesley Clark to Kerry, denied to Jay Leno that he supports the Democrats and fibbed about his advice to Nader in 2000, so who wants to be in the same corner as him, assuming he stayed in one corner long enough for anyone to identify it? Here's John Kerry, offering himself as a man of war, as a former prosecutor, as a candidate who hasn't got one single substantive, useful idea about turning the U.S. economy around and improving the overall state of the world. The only difference from Bush he can identify is that he went to Vietnam, killed Vietnamese and collected a bunch of medals, which some of his Navy colleagues who fought there at the same time say he didn't deserve.
