With those new comparison numbers, total accepted ballots are 113 percent of where the total number stood four years ago, with registered Democrats at 140 percent, registered unaffiliated voters at 148 percent, and registered Republicans at 81 percent.
Among those ballots requested and still not returned, the party registration breakdown is:
