As I wrote before:

LWers having blogs elsewhere is a good thing!

I don't expect LessWrong itself to become a good venue to discuss politics. I do think LessWrong could keep its spot at the center of a "rationalist" blogosphere that may be slowly growing. Discussions between different value systems part of it might actually be worth following! And I do think nearly all political factions within such a blogosphere would find benefits in keeping their norms as sanity friendly as possible.
