One of the most shocking ads aired this political season was aimed at a woman named Robin Hudson.

Hudson, 62, is not a congressional or Senate candidate. Rather, she is a State Supreme Court justice in North Carolina, seeking her second eight-year term. It wasn’t all that long ago when, in North Carolina, judicial races were publicly financed. If a candidate spent more than $100,000, it was unusual. Ads mainly consisted of judicial candidates promising to be fair. Any money the candidates raised was almost entirely local.

This ad in North Carolina, however, which aired during the primary season, was a startling departure. First, the money came from an organization called Justice for All NC — which, in turn, was funded primarily by the Republican State Leadership Committee. That is to say, it was the kind of post-Citizens United money that has flooded the political system and polluted our politics.

And then there was its substance. “We want judges to protect us,” the ad began. The voice-over went on to say that when child molesters sued to stop electronic monitoring, Judge Hudson had “sided with the predators.” It was a classic attack ad.

Not surprisingly, the truth was a bit different. In 2010, the State Supreme Court was asked to rule on whether an electronic-monitoring law could apply to those who had been convicted before it passed. Hudson, in a dissent, wrote that the law could not be applied retroactively.
