The most obvious one is Smith\\Approval where the voters have control over their own approval cutoffs (as opposed to implicit approval) with default approval as top rank only.The other method I have in mind is not quite as simple, but it has the added advantage of satisfying the FBC, while almost always electing from Smith.<br></div>
