That should have been the headline of a Washington Post piece on the future of the Bush tax cuts. The piece quotes Grover Norquist as saying:
"And GOP strategists say the White House’s position makes the president vulnerable to charges that he would impose what many Republicans are already calling the 'biggest tax increase in American history' if reelected. 'We’ll run against their tax increase,' said GOP anti-tax activist Grover Norquist, 'and we’ll crush them.'"
President Obama is not proposing the biggest tax increase in history. He is proposing ending the Bush tax cuts for the richest 2 percent of the population. This is not even close to the biggest tax increase in history.
If the Republicans make the charge that it is the biggest tax increase in history then they are not telling the truth. They apparently believe that the media will allow them to get away with making a lie the centerpiece of their campaign.
