Weak Acceptability factor of PM candidates '09

Heading the Indian Prime Ministerial institution is one of most challenging post in the world. Hell lot of India politicians are great administrators but toughest to achieve one of those quality is "acceptance". One of the pioneer of such quality is Atal Bihari Vajpayee. Inspite of being leader of, so called, 'communal party' he managed to create an alliance - parallel to which never existed in the Indian political history. When we look for the same in present situation, none, Dr Manmohan Singh or L K Advani, possess such quality.
LK has put a great effort in a crash course look-a-like change of image but it is not showing the results. LK is simply "unproven" for such a position according to some and, as Dr Singh has already pointed out, there is nothing significant LK has done for India yet.
On the other hand, there are (convincing) arguments against Mr Singh suggesting he is incapable of taking his own decision. He is not perceived as serious leader even within his own party.
