The R&B Committee should use the national polls to arrive at fair representation for Michigan and Florida. Then they should allocate the pledged delegates based on an average from those polls (in those states). This is the closest the Democratic Party can come to fair representation, and therefore it’s the best way to fix the broken process.
Of course, these states should be penalized for going early by losing half their pledged delegate votes. But of the half of the delegates left, they should be allocated according to what the national polling organizations show for those states.
The Democratic Party should take the percentages polled in these states over the past three months by the national polling organizations and average them. That would be reasonably representative of the will of the voters because these organizations are going out to the people of these states and polling them on what they want. It represents the best estimate of what these people want.
Splitting votes in half or using exit polls doesn’t represent these people. Taking away all of their votes doesn’t either (although it’s fully warranted, because each state knew the rules and had the opportunity to have their votes fully counted). If we are going to fix the delegate problem, we should look to the best means we have for determining the will of the voters, and this is to make use of the national polling organizations to determine it.
