Democracy lack of intelligence?

    The general opinion about the state of democracy is that this is the best form of government in human history because the opinion of majority is satisfied.I will give the same example as in the post "The power poll".In a presidential campaign there are a few candidates mostly from different parties.There are two rounds.In first round,people have more options so you have more chances to vote the contender of your soul.
  But if the elections would remain in this stage,a lot of people would be unsatisfied because the winner from the first place cannot easy gain 50%.So there the second round,which divides people between two options,the republicans/democrats for example.Until here all is good,this is green card for democracy..Also comparing with communism,where one men decided everything,here are a few man and devices,like The court,The Parliament/The Congress,some chambers and many organizations in every domain and minister.
   But if we look further,49% are controled by 51%.And it is possible that 51% to be wrong.It is possible even for 99% to be wrong,if people don't have the eye of eagle of what's happening around.
      For example Hitler was a product of democracy,in 1932 he won the elections with over 30%.This system is vulnerable by the manipulation,people can be forced to decide between two bad contenders,the least bad.
Also,the funding campaign can put in difficulty some of them which don't have such good sponsors,but have a better plan and are faithful to their cause but don't have billions of dollars to spent on publicity,TV shows,banners and parades /authorizations in public space.And more than that ,you have as a winner/loser in the campaign some obligations to the sponsors,you must protect them and even some illegalities because otherwise you'll be no more supported,neither you,nor the party you come from.
           Finally from the perspective of the human being,it is a matter of choice between a few options which divides the mind,but the mind doesn't participate with something new in the national events.It is overestimated the power the vote,because anybody can have a choice but only few can have influence and a word to say.

The power of poll

Nowadays polls are very common,everyone talks about them,and guides their opinion after them.The disadvantages are more or less subtle.For example there are made on a sample of a few thousand people which gives a good probability but mostly not exactly.For example,in politics,in the eve of elections,there are shown some contenders,from the main factions/political party,which indirectly promotes them in front of surprising/new contenders,and gives more chances to a bunch of people.Another con' would be that an opinion cannot be expressed in a choice/other and a few choices cannot cover the whole spectrum of opinions and the only option you can take in this case(of course in case you respond to the poll)is to choose others,etc.
      Also it gives a psychological meaning,because people seeing an example get more confidence in the first one/two options of the poll,or at least that's the tendency.For example,when choosing a bank/web hosting site and see a poll about which one is most profitable,and you see that X/Y is the first option in eyes of 30-40%,you might ask why is that?So the message transmitted to the brain is that there must be a reason for that Coke is better than Pepsi or porsche is better than cadillac in the eye of wealthy men.
           Finally,but not lastly,the poll is a way of indirect promoting,and the suspicion is more reasoned if these polls are commanded by some company,or house institutes.
In the campaign of elections,in my country,Romania,the poll is like a compass for the citizens,so it approaches to a manipulation device,the unprofessionalism at its climax.

Poll is related to democracy!But democracy is more powerful,it decides even the destiny of a nation.
