The reason being these national party MPs are meek lambs in front of their northie dominated high commands. They are toothless in the parliament, I am yet to see a single MP stand up and debate for the state's interests. Look at SP, RJD, TDP, DMK/AIADMK. They have a lot of advantage when it comes to bargaining resource allocation for their states, while we are taken for granted! It is time we had strong regional parties so that the entire state can develop.
