The Strategy of the third front is simple ... It is a fact that they rely more on Mulayam than on unreliable Mayawati
If she is made the Prime Minister now, Mulayam will have a chance to come back to the UP CM chair later as there is no good second rung leader in the BSP.
As of Maya, if she becomes the PM now, she can rule at most for 6 months under the mercy of the Congress or the BJP and thats it ... She can neither go back to UP nor become a PM again ...
Aint it a very clever way of displacing her on the same lines of Deve Gowda?
