This is one case where I think President Obama stealing conservative ideas could be a good thing:

Stepping firmly onto Republican turf, President Barack Obama announced Friday that he will ask Congress for the power to merge agencies to streamline government and improve efficiency...First up on Obama’s list: the merger of the Commerce Department, the Small Business Administration, the Office of the U.S. Trade representative and other independent business agencies into a new, unnamed Cabinet agency to create a more efficient experience for businesses.

Virtually every Republican candidate has some item on their platform that resembles this proposal, and they're probably right to focus on streamlining: The federal government needs some simpler way to manage inefficiencies within itself. While the presidency doesn't need any more powers, Congress simply doesn't have any authority when it comes to managing government efficiency.
