In comparing the European Union Legislator and US Election procedures, I'm afraid that you didn't input the choice of answers to be selected. But I am sharing you what details I have between each others differences.
1. Historically, US was born more than 200 years ago, out of a will of the British colonies to
release themselves from the Crown. Europe, on the contrary, has been
built less than one century ago, little by little, block by block.
2. Europe is still missing to unify all its citizens is the election by universal suffrage of a President. American President’s election brought together all Americans - and this
even if the power remains de facto quite limited. On the other hand, in
the European Union, the parliamentary elections are marked by a
decreasing participation rate.
3. Founding Fathers. In the USA, it is common to refer to them in political discussions,
whereas in the EU few citizens even know the names of the founders of
Europe, and even less the principles which guided them.
