Especially, I will be pleased to read about this question but treated outside the work of Derrida. For example, Raymond Aron, in his lectures entitled "introduction to political philosophy", also asked himself to what extent a democracy can protect itself against its ennemies.
This topic appears in the curriculum of a module on 'leadership and democracy' here at IFLAS. It is also, of course, salient just now given what may be said to be the challenge to democracy represented by non-democratic capitalist states. Rather than rehearse familiar discussions about the comingness of democracy, or the aporic quality of democratic deliberation, I'd just like to throw in De Toqueville's remarks (in Democracy in America) about mediocrity and the concomitant attraction of wealth and corporatism as representing a neglected way in to the subject. In any case, I will watch to see what else emerges in your comments.
Thomas, I think you should read the work of Niklas Luhmann and, in particular, its application in the context of law by Gunther Teubner. His opus magnum is "Recht als Autopoietisches System", translated into many languages.
