First are the distortions. Romney says 47 percent of Americans don't pay income taxes. That's literally true, except it's misleading because it includes every retiree who hasn't enough income to pay income taxes (most retirees), every poor and lower-income person who doesn't have enough income to pay, and a few multi-millionaires (perhaps like Romney himself -- we don't know because he won't release his tax returns), who don't pay because of tax loopholes and tax-avoidance schemes. Moreover, just about all working Americans, regardless of income, pay federal payroll taxes. Everyone pays state and local sales taxes. And so on.
But the the most important revelation here isn't Romney's witting distortions. It's his indignant condemnation of almost half the American electorate. A president is supposed to represent all of America, not just the 51 percent who elect him, and have a modicum of sympathy for the less fortunate among us.
