Actually, the founding fathers of the U.S.A. knew bribery as a fact of life for a government of liberty, and freedom.  This is evident in the Federalist as well as in letters by Tom Paine and Ben Franklin, and later, in the political war between Adams and Jefferson.  Since then, every freshman political science collegiate course instructs this ineradicable blemish of a Republic.  The best answer they could come up with?  Yes.  Separation of powers a la overlord Great Britain and Magna Carta, but instead, American Constitution style (no Queen).
