Where are the independents?

Stanley Greenberg debunks the myth:

Independents are a hodgepodge; it doesn’t work to look at them as having any common worldview. There are affluent suburban voters who are fiscally conservative and culturally liberal; there are seniors, who are more populist than the population as a whole; and there are a high number of white, blue-collar voters who are deeply angry and have been explosive in election after election. In 2006 and 2008, all these groups voted overwhelmingly for Democrats. In 2010, they voted overwhelmingly for Republicans. Right now, I don’t think we have a clue where they’re going. 

I'm not entirely sure to what extent I agree with Mr. Greenberg's view. It seems, at least to me, that sometimes people are to concerned with arguing for what fits their ideology, and show little concern for simply advocating what they perceive as right. (This, by the way, is how I feel when I look at Instapundit.)
