Left does not care about Lok sabha elections. Ruling Bengal is a higher priority for them. At this point Mamata Banerjee has formed unofficial alliance with the Congress to hurt Left Front in the panchayat elections. But if BJP comes to power at the centre, Mamata will lean more towards BJP because she wants to impose article 356 in Bengal under any pretext. This will alienate Congress and the anti-left vote will be split. In other words, arithmetically Left wants to face a Mamata BJP combo than a Mamata Congress combo.
