Although the president actually discussed the idea of a "secretary of business" last Friday, Mitt Romney's campaign attacked him on it Thursday with a new ad and remarks on the campaign trail.

Twitter amplified the conversation, as usual, with the National Republican Congressional Committee (NRCC) taking the attack online and turning it into a national conversation.

The NRCC's hashtag #ObamaCabinetPositions was trending nationwide part of Thursday afternoon and devoted to jokes about other positions Obama might name in his second term.

Obama's proposal would merge six commerce and trade agencies in order to streamline the federal bureaucracy for businesses. 

"I don't think adding a new chair in his Cabinet will help add millions of dollars on Main Street," Romney said on Thursday while campaigning in Virginia.
