The invitation poked fun at the stereotypical differences between east- and west-siders in the county by, for example, listing tips on how to speak and dress like a west-sider.
The invitation's suggested attire for the fund-raiser at Western Hills Country Club: "Business attire.
Bowling shirts optional."
A west-sider himself, Bedinghaus was reported to have said that the mailing was "solely tongue-in-cheek" and that "sometimes politicians take themselves too seriously."
But some offended west-siders who sounded off in news reports apparently didn't take it as a joke.
Based on the reaction, does Bedinghaus think he should start taking himself more seriously?
"Absolutely not," he said.
The reaction to the mailing, except for a few people, was overwhelmingly positive, he said.
"I do believe that a little bit of humor in politics is a good thing," Bedinghaus said.
