POLL: Who’s the most dishonest politician?

Satirist Mark Twain once proclaimed, "an honest man in politics shines more there than he would elsewhere." Unfortunately lying and politics have often gone hand-in-hand but in recent years falsehoods and duplicity have increased by orders of magnitude in the political sphere. Moreover, truth is seemingly no longer an objective fact but determined by whether it agrees with one's ideology.

Ignoring this new paradigm, who do you believe is the most dishonest politician?
