Chuck Marr of the Center on Budget and Policy Priorities has posted on his Web site a pie chart that everybody should see, but most especially Mitt Romney. It's a breakdown of the "47 percent" of Americans (actually, 46 percent) who don't pay federal income taxes. This group was famously labelled, by the Wall Street Journal editorial page, "lucky duckies."

Here's how Romney, in his demented talk (since disavowed) to rich donors in Boca Raton, broke the duckies down (I will never get tired of this quote):

All right, there are 47 percent who ... are dependent upon government, who believe that they are victims, who believe the government has a responsibility to care for them, who believe that they are entitled to health care, to food, to housing, to you-name-it. That that’s an entitlement. And the government should give it to them. And they will vote for this president no matter what…. These are people who pay no income tax. Forty-seven percent of Americans pay no income tax. So our message of low taxes doesn’t connect. ... And so my job is not to worry about those people. I’ll never convince them they should take personal responsibility and care for their lives.

And here is how Marr breaks them down:

Sixty-one percent are working duckies. They just don't happen to earn enough to pay income tax. They do earn enough to pay highly regressive payroll taxes, excise taxes, and state and local taxes. For the bottom quintile that constitutes, respectively, 9 percent, 2 percent, and 12 percent of their incomes.
