Jaded,

There could be a real cost savings with this bill.  Supporters should present the total cost of printing the "business return envelopes" vs the present non-postage paid envelope (if any) and the postage to be charge for each one returned.  Then compare it to eliminating the drop boxes and the cost of all the vehicles and people going around picking up those ballots and returning them.  The results could be a net savings, net wash, or net increase (small, medium or large).  It would eliminate all the other arguments if the first two possibilities turned into facts.  The other pro arguments would apply if it raised costs by one of the three categories for net increase.  Maybe the democrats do know this number and just don't want to release it, who knows?  Why make an informed decision when one can just guess?

P. S. There could also be a carbon reduction savings here by letting the USPS pick-up the envelopes as opposed to all the others vehicles running around.
