Dynastic politics is common enough throughout South Asia not to shock. Father to son or daughter, or spouse to spouse, the handover of government and party leadership through patriliny or matrimony is a constant. The United States seems the only other place in the world where political dynasties have delivered governors, senators and presidents with similar regularity.
There is family rule elsewhere to be sure, not forgetting Bashar al-Assad in Syria, Kim Jong-Il in North Korea, Megawati Sukarnoputri in Indonesia, and Raul Castro, who has just followed brother Fidel, in Cuba. But it is in South Asia that political dynasties find the soil to be the most fertile, and the glamour of the political nobility rivals only that of the long-standing monarchies of Bollywood.
