Even if the government falls, there is no respite to you knickerwallahs or commies.
1. In whole of South India, BJP will find it difficult to open its account. This despite BJP forming the government in Karnataka last month. A Congress-JDS tie-up gives them 55% vote share, adequate to ensure a complete white wash for the BJP who would lose their 18 seats they hold currently. In Tamil Nadu, the DMK alliance sits quite pretty and AIADMK will certainly not enter into a pre-poll pact with the BJP. Chandra Babu Naidu in AP will do the same, tying up with the Left instead. In Kerala, the BJP is a non-player.
2. BSP cannot likewise enter into a pre-poll pact with BJP because to protect its Muslim votes. So the BJP is destined to third place at best - losing 15 seats it currently holds.
3. In MP, Orissa, Chattisgarh and Rajasthan, the BJP governments faces huge anti-incumbency. Accordingly expected to lose significant seats it currently holds.
This is only a short list. So except for small states like Delhi, Haryana etc, there is no space for the BJP to makeup its loses, leave alone forge ahead from its current tally.
The Left is in a similar predicament. It is poised to get completely white washed in Kerala (where it now holds 20 seats). In West Bengal it is expected that TMC-Congress tie-up will make a huge dent.
So except for their public posturing, both BJP or Left do not want immediate elections
