With the massacre in state assembly polls and the current losses in bye elections, SP and Mulayam now that if elections are held right now they will be wiped off to a much larger extent. And worse still it'll be Mayawati which be gain all the power they lose. Their only hope is to keep this govt alive and try to find some means to bring BSP and Mayawati's influence under control before the next general elections.
SP and Mulayam are even more desperate than Congress party at the moment to keep this Lok Sabha from dissolving.
