Prakash Karat and his party did their utmost to protect the interest of the country *as they see it*. They did not horse trade and their MP's did not cross-vote (the actions of the speaker notwithstanding). If all political parties emulated the Left, democratic institutions of the country would be strengthened.
Its fine to disagree with the political agenda of the Left -- which is after all driven by the interests of the class of people not represented in the Rediff readership -- but personal attacks on upright political leaders like Karat (or for that matter Advani or Manmohan Singh) shows that you have no respect for the democratic process.
