I think the demand for rotation of the chief minister's post in Penang is because Umno is unable to practice the politics of patronage so vital for their survival.
They are unable to give out contracts to their cronies. If that is what Umno wants to do, then we in Penang should kick out the BN government, especially Umno, in the next election.
Then there will ne no need to rotate the CM's post.
Umno must realise that BN does not automatically form the next government. So it would be wise if they don't demand for top posts until after they form the next government - if they can.
We must teach BN a leason in the coming election.
