Political advisor is only one advisory role though, and somewhat divorced from policy. Let the experts determine how to navigate the desired policies through the political system, sure - but political and policy advice are not necessarily one and the same.
For example a policy advisor makes recommendations to an organisation which once adopted as a desire by that organisation (in this case the AMTA) the political advisors then will help the organisation to determine how the policy goals are steered through the political system towards the desired end. You have carefully stated that you are not a political advisor and steered the conversation away from the concept of policy. Are you saying to have no advisory input into AMTA at all or are you just trying to cloud the issue with smoke and mirrors?
