The Republican gubernatorial candidates targeted Pat McCrory Tuesday night.
"It's amazing to hear Pat talk about he wants to cut government when he's the big mayor of the biggest city in North Carolina and has the highest tax burden," Smith said.
McCrory said that he hasn't supported a property tax increase since becoming mayor in 1995.
Orr argued that Charlotte keeps property taxes lower because the city involuntarily annexes sections of Mecklenburg County every few years.
McCrory said he learned how to take criticism as mayor.
"It is a little disconcerting that someone is more interested in attacking my record rather than stating their own. And that's the kind of politics we don't need," he said.
