Congress used Mayawati for a short term - to get their nominee elected as President. Mayawati got her cases disposed in turn. Then Congress and Mayawati dumped each other. Now Congress is using Mulayam for Nuclear Deal. Mulayam will use Congress to embarras Mayawati, his political enemy.
This is a short term opportunism where these politicians are completely ignoring the public's woes like sky rocketing commodity prices, high inflation, fuel prices, high interest rates, falling industrial output etc.
They will pay heavily for this as Nuclear deal has nothing to do with common man. It is a US agenda and the Central Govt is under extreme pressure from US to fulfil it.
