Former Douglas County Assistant Deputy of Operations Kris Pierce kicked off his campaign on Tuesday.
Pierce said he was let go in February after advocating on behalf of Douglas County taxpayers. County Assessor Diane Battiato said his position was eliminated due to cuts.
On Tuesday, Pierce took aim at this year's huge valuation hikes.
"Even more troubling, the current assessor knew there was going to be this drastic increase and did nothing to warn taxpayers about what was to come," Pierce said Tuesday.
Battiato, who said she plans to run for re-election, pointed to the market.
"We came in, we followed state mandate, we did the job we were supposed to do,” she said. “The problem is that you just don't know what the market is going to do, but you have to follow the trends and sales and value accordingly."
