Partly Facetious - can we have same party heads for more than two terms?

"So there are to be new rules and regulations for those who wish to stand for the 2007 elections."
"Well, Musharraf code of rules and regulations states that a BA is essential for any aspirant and this in a country where education is sooo low..."
"Yeah, but the leaders must have a BA."
"President Musharraf has a BA?"
"Yes, I think so, though I know that they take you in the army even with an FA degree! The Chaudhry cousins have BAs as well, I think. Hey, even Nawaz Sharif had a BA."
"So you are saying it couldn't be too difficult to get a BA in that case."
"Right, I mean let's be honest Nawaz Sharif was not know for his general knowledge."
"Anyway, another rule is that you can only become the PM twice in your life time. And guess what! Both BB and Nawaz Sharif have reached that magic number."
"Surprise, surprise! What about a President? Can he be President for more than two terms?"
"An entire term or are you referring to years in power?"
"What's the difference?"
"A big one, my friend! BB and Nawaz Sharif both didn't complete their terms and together had power for less than the President has had so far." "You are steering real close to making an anti-state comment." "Right, so what's the new rule?" "Parties must hold internal elections for leadership."
"Can a person who has been a PM twice stand for party leadership?" "That is a good one and one has to appreciate the ingenuity of Durrani to bring that point up. I mean would Sheikh Rashid have thought of that!"
"No Sheikh was a more direct man. BB and Nawaz Sharif are bad people and Musharraf is a real prince amongst men, sort of a bloke."
"Before you become too enamoured of Durrani, he also said that President Pervez Musharraf was willing to resolve the internal problems of all opposition parties, including the People's Party Parliamentarians and the Pakistan Muslim League (Nawaz); just like he was doing for the PML (Lotas)." "That's even better than Sheikh Rashid. Maybe we will have fun with Durrani after all."
