Best of the Web Today - WSJ.com: "'I took the liberal view for many decades, but I believe I have changed my mind. As a child of the '60s, I accepted as an article of faith that government is corrupt, that business is exploitative, and that people are generally good at heart.... [Now I] question my hatred for 'the Corporations' -- the hatred of which, I found, was but the flip side of my hunger for those goods and services they provide and without which we could not live. And I began to question my distrust of the 'Bad, Bad Military' of my youth, which, I saw, was then and is now made up of those men and women who actually risk their lives to protect the rest of us from a very hostile world.... I began reading not only the economics of Thomas Sowell (our greatest contemporary philosopher) but Milton Friedman, Paul Johnson, and Shelby Steele, and a host of conservative writers, and found that I agreed with them: a free-market understanding of the world meshes more perfectly with my experience than that idealistic vision I called liberalism' -- Playwright David Mamet, writing in the Village Voice on why he is no longer a 'brain-dead liberal.'"Three cheers for Mamet for learning to think for himself and for having the guts to "come out" as a conservative.
His work includes: Wag the Dog; The Verdict; and Glengarry Glen Ross.

Article by Jonah Goldberg about reactions to Mamet's revelation, ranging from "Ignore him and maybe he'll go away" to "He was never that good anyway."
