A voting system is demonstrated which meets Arrow's 5 conditions and also satisfies the Gibbard-Satterthwaite demand for strategyproofness. The strategy is contained in the voting procedure itself so voters are incentivized to vote sincerely. This procedure allows for the circumventing of Arrow's Impossibility Theorem.
