It appears political bias has crept into the commissioning of portraits of alumni to reflect the diversity of Princeton (On the Campus, June 6). For example, former Democratic Sen. Bill Bradley ’65, but not Republican Sen. Ted Cruz ’92 of Hispanic descent; and Democratic Supreme Court Justice Sonia Sotomayor ’76, but not Republican Justice Samuel Alito ’72 of Italian descent.

Are Republicans eligible?
