Fewer than 20 percent of the provisional ballots cast in the election two weeks ago by voters who didn't have the required photo ID were counted.
The preliminary tally comes Tuesday from the Wisconsin Elections Commission.
The commission says there were at least 750 provisional ballots cast in the Nov. 8 election and of those 618 were issued because the voter didn't have an acceptable photo ID.
Only 116 out of the 618 provisional ballots were counted. Most of them, 399, were marked as "deadline expired," which indicates they weren't counted.
Another 278 were outright rejected and 224 had no information reported on their status.
This was the first presidential election where voters were required to show a photo ID.
Opponents of the law say it repressed Democratic voter turnout, particularly in Milwaukee.
