This week, President Obama decided to no longer defend the constitutionality of the Defense of Marriage Act -- a decision that, in another time, would have been expected to prompt major blowback. The fact that it didn't is another indication that social issues no longer pack the punch they once did. Elsewhere, the fighting escalated and an embattled strongman stuck back aggressively. I'm talking, of course, about Charlie Sheen, who unleashed a series of ugly diatribes aimed at his producer, Chuck Lorre, prompting CBS to pull the plug on Two and a Half Men for the rest of the season. If this is a harbinger, The Fighter will take home the best picture Oscar. But the buzz at all the pre-Oscar events is that it's a two-film race -- The King's Speech vs. The Social Network. What's your prediction?
