In addition to the confirmation vote by the Parliament (which will be tough this time ... considering the president only had a single vote majority) they are also nominated by the national governments (each government a commissioner) thus the differences in countries are represented as well. This is more democratic legitimation than most ministers in most state governments have, where ministers are often appointed by the head of government without confirmation. (The EU commission is similar to a government and commissioners are similar to ministers in their role)
