Adult Video Star.

Although Both Occupations are Professional Liars:

AVS - Oh, I want you so bad. I'll be so good to you!
Politician - Oh, I want you so bad. I'll be so good to you!

AVS - I'll screw you.
Politician - I'll not screw you.

The AVS wins, because they're better looking. (At least if you paid more than $1.99 for the DVD! )
