Bill Clinton

One can only hope to achieve half this level of mastery in a lifetime. An impossibly accomplished person sounding authentically down-home, breaking it down without dumbing it down or making the audience feel dumb, speaking to millions as if to his best friend over a beer, twisting a shiv into his opponents with an affable smile, and delivering passion, information and guidance in copious amounts as if that was the easiest thing in the world. Easily one of the best communicators in the world.
