No Sir, I don't like it.
It will only serve to increase the bad blood between "opposing" members, and that will bleed over into other areas of the forum. It'll just be a rehash of the W&P threads from RS and GH, three and four years ago, and nothing positive or beneficial ever came out of those. Everybody's still on the same sides that they were back in those days.
There are plenty of other forums out there already for people to talk politics, and as much as it might be nice for JD to be one of the "big" SW forums that allows political discussion, I think the negatives would soon outweigh the positives.
And, "unmoderated forum" or no, that's still not gonna change the fact that George Bush sucks donkey balls.
