Daniel Henninger in the Wall Street Journal:
They expected to take losses in November. What they got instead was Armageddon. Suddenly an authentic reform movement, linked to the Republican Party, whose goal simply is to stop the public spending curve, had come to life.
Against that grim result, every sentence Messrs. Krugman, Packer, Alter, the Times and the rest have written about Tucson is logical and understandable. What happened in November has to be stopped, by whatever means become available. Available this week was a chance to make some independents wonder if the tea parties, Sarah Palin, Rush Limbaugh, Glenn Beck and Jared Loughner are all part of the same dark force.
