This isn't so much of a problem if it all leads to a more effective political system. (Although, what's the chance of that?) But it does mean that voters may get left behind as the debate hops about from pillar to post. And when the debate's effectively about the gap between the voting and the political classes, that could be a destructive state of affairs.
To my mind, there's a great political victory to be won by the first party to set out all (or most) of the different positions on constitional, electoral and parliamentary reform; to do so concisely and clearly; and to somehow involve the public, armed with this new information, in coming up with a resolution. Quite simply: if they're going to make the case for greater openness and transparency, then that case needs to be open and transparent in itself.
