Re Obama's Liberalism (I would say Leftism), from Beston at TCS as quoted in a piece by Ed Driscoll:
In arguing that "labels don't apply anymore," Obama is making the same claim, nearly verbatim, that Michael Dukakis, John Kerry, and other Democrats have made over the years, stretching back over a generation. What these candidates found out the hard way was that labels mean plenty, especially when they refer to something that people understand--like liberalism.
Americans learned over several decades what liberalism, at least modern liberalism, was all about. Contrary to some claims that conservatives, in a sinister plot, defamed the word, liberalism did a pretty good job defaming itself: from the anything-goes ethos of the 1960s to radical war protestors, from tax-and-spend government and welfare policies to lax criminal justice, pacifism abroad, and a wide-ranging contempt for the institutions and values of American life, liberals took what had been the dominant political current in American politics and made it into a pejorative term. Today, while centrist American voters may blanch at some of the Republican Party's positions, they have no wish to go back to governmental progressivism.
If they did, Obama-never one to miss a rhetorical trick--would be resurrecting the word "liberal" as change we can believe in.
