Does the structure of the Executive really matter?

There isn’t an ideal structure of democracy as leaders will make us believe. While some are proposing a powerful prime ministerial post and a ceremonial presidency, others think the status quo has no problem.
After all, we spent many years fighting the imperial presidency we discarded in 2010. We are forgetting too quickly before we entrench institutions that will protect those in power when they join the ranks of ordinary citizens.
It is imperative that we learn from the British and Americans who are currently faced with constitutional predicaments.
True leadership will always emerge and disrupt status quo even when unexpected as it happened with President Obama.
