Is ObamaCare no longer the silver bullet for conservative campaigns and the third rail for liberal ones? According to a report by Bloomberg, Republican candidates are switching much of their rhetoric on ObamaCare for other issues. In North Carolina, for example, Republican ads mentioned ObamaCare 54% of the time in April. Months later, in July, that percentage of ads devoted to the issue fell to 27%. While the Left sees this as Republicans backing away from the issue, David Harsanyi pointed out, “consider that a quarter of all political ads running in North Carolina attack Obamacare specifically. This seems to suggest that it’s still a comparatively ‘major issue.’ Or, let’s put it this way: Is there any other law in the United States that eats up more political space?” But the Left is creeping from their ObamaCare-foxholes. Mark Pryor ran an ad in Arkansas boasting for his support for the law. Pryor just stepped on the third rail.
