That was misleading. The voters were issued a two-page ballot and the county reported the number of pages voted (which was slightly less than 2 pgs/voter, as a few voters only voted one page and overlooked the other).
Actual voter turnout was more like 70% -- which is still suspiciously high for the county.

that is a problem and more than 70% turnout
