To see why Cthulhu is the best choice for ongoing evil lets compare the current president with all the candidates:

George W Bush
Super evil, Responsible for thousands of deaths and the suffering of hundreds of thousands of people

Cthulhu
Super evil, Responsible for thousands of deaths and the suffering of hundreds of thousands of people and has super cool wings and tentacles

Obama
Not evil, no wings or tentacles.

McCain
Not evil, no wings of tentacles (but does have a nice turkey neck)

So as you can clearly see the other candidates really don't have anything going for them at all.
