Republican candidates running for elected office in Hall County have been asked to sign a No Tax Pledge this week during the qualifying period. And while pledging not to raise taxes is standard procedure for most conservative candidates, the issue has politically charged the race for local Board of Education posts after some incumbents seeking re-election declined to give their John Hancock to the document. The Hall County Republican Party began circulating the pledge in 2010, piggybacking on a similar campaign targeting elected officials in Washington.
