Waukesha County Clerk Kathy Nickolaus, a former staffer for the Assembly Republican Caucus, has been sharply criticized in recent months for her handling of recent elections. Even the archly-conservative Waukesha County Board has sharply condemned Nickolaus after past elections, demanding an immediate audit of her practices following ominous red-flags that emerged regarding her lack of oversight, failure to create backup files and her stubborn insistence to “keep everything secret.”

The County auditors said it was eminently possible -- including historical precedent -- for Nickolaus or a rogue employee to tamper with data. Why? Nickolaus insists on controlling password access and has unilaterally decided to move sensitive files, like election results, onto her personal computer.
