Left parties got enough influence in India than many regional parties and it is increasing. Just check the nummber of seats they are getting in each election... It is just increasing.. They got the most number of seats as a block after Congress & BJP in last elections. They rules 3 states... Left parties & their ideologies are part of India & it's History and nobody can deny that..It will remain as same. In a caste & communal politics ,left are the only hope..
