I'm a bit biased (a lot maybe). I voted TOP in the last 3 elections, and will be this election.

National and Opportunity have a few things in common and a lot of things that are in conflict.

I think the key difference between Opportunity and every other party; is that evidence forms the basis for all of the policy. The other parties have a policy position and then search for evidence to support their preconceived ideas. Political parties are not scientific institutions and thus, will never be called out for this...but to me that is not a way to come to such important decisions.
