"I don't think he's negative and I don't think I'm negative. These are issues and they're brought up," said Mayor Martin.
If you ask Glen Robertson, the target of the ad:
"I can't control what my opponent does, the only thing I have any control over is my campaign
My personal feeling is at the end of the election, I'm going to still have my honor and integrity and that's more important to me than winning the election," said Glen Robertson.
But Mayor Martin says he's focusing on the issue of property taxes.
"My opponent had sent out a mailer last week raising some of these issues and so we came out with ads that give our side of the issue," said Mayor Martin.
And says it's not necessarily an attack.
"If he was making disparaging remarks about my family, my religion or something of this nature, that would be an attack ad. I don't think people enjoy that type of campaigning, and I like other people have been watching the national campaigns and I think you should stick to the issues and the issues are taxes," said Mayor Martin.
Robertson says there's no reason to respond.
"I'm going to stick to talking about issues and solutions because I think thats what really voters want and need to hear about," said Robertson.
