from Mona Charen at National Review, How Bernie Sanders Became the Conscience of the Democratic Party

No problem, the self-described socialist counters, he will raise the money by taxing the “greedy one percent.” The problem is — arithmetic. The top one percent already pays 45.7 percent of all income taxes. The federal government brings in about $1.5 trillion a year in tax revenue. Even if you confiscated 100 percent of the earnings of those making $1 million or above, you’d only net $616 billion, not nearly enough for Bernie’s wish list (to say nothing of the depressing effect on productivity such taxes would have).

Without Elizabeth Warren in the race, Sanders has become the conscience of the Democratic party. They fulminate about the rich, promise the moon, and flunk math.
