Thumbs Down to Dallas County Tax Assessor-Collector John Childs and the handful of other county elected officials who insist on having the taxpayers help pay for their political advertising. Every piece of corre-spondence mailed from the tax office, including thousands of property tax notices, bears the name “John Childs” in big letters on the envelope. The city tax department doesn’t follow the practice; but then the city tax assessor is not an elected official. County commissioners are notorious for putting their names on county property. Isn’t it time we stopped financing this childish practice?
