My vote goes to Dana White! 

President of the UFC.

The Ulitmate Fighter reality show series...  Think about this.

While the show airs "live" fights every week..  The actual combat took place several months ago.

Yet nobody knows who won any of them.... 

The Whitehouse can't stop leaks

The Senate and Congress can't stop a leak.

It was a leak that eventually turned up Saddam hiding in his hole.

Dana White is leak proof!

Thus

The worlds most powerful man.
