N.C. Senate Republicans promoted a pair of Daily Journal columns this week from John Locke Foundation President John Hood. One discussed myths about the impact of emergency room visits on total health care costs. The second discussed post-Katrina education reforms in Louisiana. Meanwhile, FreeRepublic.com highlighted Hood’s column on Gov. Beverly Perdue’s dubious explanations about the unreported campaign flights that generated a $30,000 fine from the State Board of Elections.
