Since 1999, Ponnuru has been either a senior fellow or senior editor, or both at the same time, at "National Review", where he frequently writes and comments on politics, public policy, economics, the law, and even faith. In its pages, he has called for a revival of Republican policy thinking by applying conservative ideals to contemporary problems and emphasizing the concerns of the middle class. He has been a leading conservative voice in making the case for increasing the child tax credit to properly compensate parents for the cost of raising children, and won praise for finding common ground with progressives and Democrats on the issue. He has also been a regular co-author and leading voice with economist David Beckworth on the topic of monetary policy and market monetarism.
