Every study that I have seen shows that my Mormon neighbor is, indeed, most often a model citizen. The Mormon church seems remarkably presentable in the public square even if disreputable company for the church social.
If the Romney candidacy does anything, it should pose the hard question to Christians of why this is the case. What can we learn from the remarkable Mormon commitment to education and social welfare for its members? What can we learn from the high levels of patriotism and civil involvement?
