OK so the new President of Earth is a Dolphin alien mutant in disguise. 

The synthetic skin is perfect and except for his high pitched voice  no one would notice anything strange

I should have knocked I suppose, but then I wouldn't have seen him in his pool 

He can't be any worse than the last one and the Earth is mostly ocean, so who better to be in charge.

No Mr President I won't tell anyone so long as you give me that position as agreed, You can rely on my discretion.

Any way, Who would believe me?

What I saw was far beyond chilling.

The President removed his head from the rest of his body with his own hands. I realized they were not human hands. They were machine. The President of Earth had just been elected and none of the voters knew he wasn't "he" at all. Why? What was its purpose? Was it benevolent? Malevolent? Neutral? 

Despite the feelings of fear, I had to smile. It all made perfect sense now. Why President Ainson never fabricated the truth; why the President never made a mistake while speaking; why his brilliance was so renowned globally. 

Wow.
