Virginia Thomas is no ordinary activist. In fact, she’s the wife of Supreme Court Justice Clarence Thomas and she has founded a Tea Party-linked group, which could stretch the court’s traditional sense of impartiality. Thomas’ new group is called Liberty Central Inc. It’s a nonprofit lobbying group set to issue score cards for Congress members during the November election. The group and work doesn’t violate ethical rules for judges, but it could potentially be grounds for conflict of interest for her husband. Liberty Central may be a nonpartisan group, but it leans toward conservative principles and its nonprofit title allows it to raise unlimited amounts of corporate money without disclosing its donors. The group is set to launch fully in May.
