Dennis Prager, the Jewish columnist, writes a handy little piece with which a Lutheran like me can agree. "In Politics Values Matter, Not Theology"
Prager may use some different lingo than we may, "morals" instead of "civil righteousness" for instance...
I also agree with his take on the objection many Christian have with Mormons - that it would be less strenuous if Mormons didn't insist on calling themselves Christians.
I guess, having said all this, I too would echo Prager:
"None of this is an endorsement of Mitt Romney's candidacy or of his values. It is an endorsement of the irrelevance of his theological beliefs. "
