Politicians and Journalists:

In a democracy, Politicians hold major role in country because we elect them to make our laws: they give legitimacy to our system above all others. Every democratic nation’s politicians are greater because they are elected, they make laws and some of them serve in government. Their functions as representatives legislators and executives give them a status within national life which is uniquely important: that of being the supreme expression of the democratic country.
I think politicians derive their authority from people sometime and in that case the media and journalist must strive to represent the interests of the people. Journalists do that partly by asking the questions witch people want answered however uncomfortable that that may be for politician. I think we cannot nourish democracy by “protecting” politicians if anything, we weaken it. And there is one more question arises, can media claim as opposition of politicians in that case? Of course not because it would be an abuse of their power (lets use the word “influence” to power) if they claimed to be real opposition to the government or related bodies.
Journalists and media play necessary democratic function (as against commercial function) is to provide information as fully and fairly as possible, which will allow those to make informed judgements-including about those they choose to govern them; and to act as media for diverse opinions.
