So John Burton, chairman of the California Democratic Party, is in trouble for letting his mouth eclipse his brain. Not much new in that. But this time Burton has outdone himself. He equated the Republican Party to Nazi propagandist extraordinaire Joseph Goebbels. That is one of the ugliest and most offensive comparisons that can be made in American society. It is akin to hate speech. Such hyperbole has no place in American politics. It just doesn't. And, frankly, to advance such a notion is simply mean-spirited and displays profound ignorance of history. If we are to have any hope of elevating the level of political discourse in this country's campaigns, we simply must not allow such comparisons to enter the fray.
