It seems the Obama campaign catchphrase of the month is “trickle-down tax cut fairy dust.”

President Obama has used the term to describe Mitt Romney’s economic policy in five speeches over the past week.

“Look, Orlando, we know better. They have tried to sell us this trickle-down tax cut fairy dust before,” Obama said at a Rollins College event in Winter Park, Fla., on Aug. 2. “And guess what — it didn’t work then; it will not work now.”

“We know better than this. They have been trying to sell us this trickle-down, tax cut fairy dust before. We’ve seen this before. And guess what — every single time, it doesn’t work,” he said later that day to a crowd at Loudon County High School in Leesburg, Va.

“So there were all kinds of different gymnastics being performed by the Romney campaign last week. They have tried to sell us this trickle-down, tax cut fairy dust before. And guess what — it does not work,” Obama said Monday in Stamford, Conn.

“So they were twisting and they were turning and doing backflips, and trying to say, well, this is a biased report — despite the fact that the head of this nonpartisan center used to work for President Bush,” he said yesterday in Grand Junction, Colo. “But it’s not surprising that he was trying to scramble a little bit, because they’ve tried to sell this old, trickle-down tax cut fairy dust before.”

And today at an event in Pueblo, Colo.: “Now, you know what, they have tried to sell us this trickle-down tax cut fairy dust before. It did not work. It did not work then. It is not going to work now.”
