I think this is a fantastic idea -- it seems the trend today is to inject politics into absolutely everything. In the past, the prevailing wisdom was to avoid political and religious topics in the workplace and technical spheres (conferences, message boards like HN, etc.). Focus on the tech and just the tech and you'll be surprised how much nastiness is naturally eliminated from this board.
And as one, the community set down the Republican / Democrat placards they had so crudely been swinging against each other ... and picked up once more the placards for vi and emacs.
