All the people named so far all have the means and resource to become PM. But the question is, do they have the brain to be good PMs and guide this ship in the right direction. The leaders that display some signs of hope for what we should expect from future MPs include;
1. Sam Basil (top of the List - Doesn't care about who or what - fights for his people),
2. Pawas Pakop,
3. Charles Abel,
4. Peter O'neil, (bit of gray area there but he's promising as a Prime Minister and so far he seems better than the ones before him)
5. Dame Carol Kidu (Unfortunatley retiring but she has her intergrity, which all others should be learning from)
6. James Marape
7. and a few others.
But this is just my opinion and may differ from anyone elses. And justy adding to a comment above, should Paias Wingti be re elected in 2012, he may become the PM.
