Eric, for numerous reasons I picked two from each party, the hope is in the discussion, picking two candidates from each party prevents the "endorsment" issue. An interesting note, since you mention Huckabee here is that both Huckabee and Obama have expressed appreciation for each other in various forms. As to hope offered on any particular issue, there are Christians, in Kansas especially who are Anabaptist and quite involved in the peace, and social justice issues illustrated in Scripture that would also have issue with Paul, and Huckabee. In fact I would venture to say that in those circles, many are supportive of Kucinich. I think an interesting point of discussion here, is that the Republican Party does not have a monopoly on "religious" issues.
I really tried to present a varied perspective in the article, I must also note however that I have already received 2 emails from Fundamentalists who speak of Obama's "Islamic" beliefs. Strange since those rumors have been dispelled many times now. One may not like his political views, but one has to be careful about the false statements made, on both sides of the political spectrum, and especially as of late, even within each party.
Again, purpose is for discussion, and even some challenge to get people to think. I could pick a candidate I presently like and will likely vote for, but those discussions are for private, person to person discussion. Will be glad to go there if you want.
