I tend to agree with this view. Why expose yourself to attack when you can sit pretty attacking the policies of the ruling party and let the whole government machinery respond to the issues? You only do that when you want to show how smart you are but don't underestimate from how many angles your grand plan can be attacked. Furthermore the person to defend the plan has to be the elected member, not the architect of the plan. Why be the target practice? If you wish to show your smartness, do it in a public forum and have all your experts present to answer questions. The scrutiny of your plans would be less immediate and you would also have more time to respond. Better if there is no response from the govt directly, which is to be expected. You can further boast about it.
