Grudem begins with a clear statement of his position on the matter:
As an evangelical professor of Bible and theology, I have decided to support Mitt Romney for President (even though he is a Mormon) for two old-fashioned reasons: First, he is the best-qualified candidate, and second, he holds moral and political values consistent with those in the Bible.
The rest of the article reads like a systematic theology paper. He clearly addresses why he thinks Romney is the best-qualified candidate, why he thinks Romney holds values consistent with the Bible, questions about Romney's religious views and their impact, and finally Romney's ability to win.
I thought it was helpful. What do you think?
