Here's some more commentary on coalition maneuvering that summarizes what LEvko has been pointing out for a couple of weeks. If it comes down to dissolving Parliament and calling for new elections, I think that Our Ukraine will be the loser. They just won't show up to vote.
Will that mean Yuschenko won't do it? No, he might just do it anyway. It could be that he is operating on some kind of principle and dissolving Parliament might be consistent with that principle. This is just to say that anything might happen.
