I don't know why you would bother to reply if you are going to assume that level of ignorance.
Yes,the parliament exists. I have voted for members of it. It is the most democratic part of the EU. The rules give it much more influence than hereto. But it has problems.
1) The Council, which is not so democratic, can veto it
2) The parliament is huge, so each member has very limited influence
3) Because of 2) it has not succeeded in creating an EU 'public sphere' or 'demos'. The 'parties' are just agglomerations of national parties. When you think of EU politicians, who are the big names? They are a) national figures and , b) Commissioners. Rarely do parliamentarians become well known,and usually for some other reason (Eg Nigel Farage).
I stand by my statement that the EU would be much more democratic if the council were elected. Firstly, do you really think the US was not more democratic when the Senate became elected? Secondly, it would mean that there were 'big figures' that get elected at an EU level. That would get the pubic much more interested and that is a significant part of what it means to be democratic. It doesn't matter how democratic the rules are of nobody cares.
