WaPo:

As they head into the 2012 campaign, Democrats are changing their definition of what it means to be rich. Forget about families making $250,000 a year. Today, the party is only interested in millionaires.

In speeches across the country, President Obama has vigorously demanded that “millionaires and billionaires” pay “their fair share” in taxes. Last month, the White House said tax reform should ensure that billionaires such as Warren Buffett pay at least as much of their income to the Internal Revenue Service as middle-class taxpayers do.

This must all come down to a matter of language. When the common American hears "$250,000," he/she does not think "rich." The word "millionaire," however, has this desired effect. The shift by the Dems is much like the GOP's brilliant transformation of "estate tax" into "death tax."
