Bernie Sanders and Martin O’Malley closed with nods to immigration reform, as ABC forgot to ask directly.

Sanders touched on his immigrant roots and talked about his father coming to the United States from Poland. O’Malley uttered the phrase “path to citizenship.” But these passing mentions do not add up to a substantive policy discussion. As many immigration reporters and activists noted, ABC News could have skipped the “first spouse” softball and gone for an in-depth question on comprehensive immigration reform.
