"Under democracy one party always devotes its chief energies to trying to prove that the other party is unfit to rule – and both commonly succeed."
— H L Mencken

Found that on the Times of India Website. Struck me as very true....I just wish they would stop bickering and get on with it. If parties spent less time on finding reasons for why the opposition is wrong, they would have more time to concentrate on their own policies ideas.
Personally I find someone who has thought through they're ideas and can explain them throughorly and clearly upon questioning, much more convincing than someone who says "well they're wrong so anything I come up with is better than that."
