The GOP did this very thing with the Evangelical set back during Reagan's first run.  I fail to see why it's OK if the GOP uses religion to further their political fortunes but dastardly if the Democrats do it.  I also fail to see why AB Chaput thinks he can attack the Dems while using his own pulpit to support the GOP, and then there is the take over of the KofC by GOP interests like Carl Anderson.  It's politics and both parties do it.
