Neuhaus, 68, is well-prepared for that role. As founder of the religion-and-policy journal First Things, he has for years articulated toughly conservative yet nuanced positions on a wide range of civic issues. A Lutheran turned Catholic priest, he can translate conservative Protestant arguments couched tightly in Scripture into Catholicism's broader language of moral reasoning, more accessible to a general public that does not regard chapter and verse as final proof. And there is one last reason for Bush to cherish Neuhaus, who has worked tirelessly to persuade conservative Catholics and Evangelicals to make common cause. It's called the conservative Catholic vote, and it played a key role last November.
