(the answer being Romney, obviously)
Well, taking that a bit further, in whom should citizens loving the values of our forefathers have voted for in the primaries, and that would be neither Obama nor Romney. But we are now faced with distasteful choices in the general election.
However, the title of the article is specifically limited to address the segment of the population who are, within the text, identified as regenerated believer-disciples of Christ -- not just persons who simply practice religious formalities prevalent in Christendom and thus call themselves "Christians." Thus for the constituents addressed, your question is another question, but not a "better" one.
With sincere regard --
