labour party problems

was just watching gillards talk about how the party was not equipped for the changing individualistic needs of the people and that the labour principle of one fits all is off the past. i wonder what would happen to a labour mp if he expressed his individualism and voted against the carbon tax- i would suggest career over. party politics may offer some stability in government but clearly surpresses free thinking. a lower house held by independants like in australia does cause uncertainty for sure but obviously improves that freedom of thought. the true independant thought comes from the people- my local mp- although democratically elected by the people, truly needs the right to freely express views of his represented people. crossing the floor in parliament should be a normal occurrence, not a career defining event.
