European democracy is an oxymoron
The digital commissioner is a member of the European Commission.
The European Commission is the executive body of the European Union. This 28 strong body is selected by the European Council (1 member per state).
The European Council comprises the heads of state/government of each country.
The European Parliament (the only bunch actually voted for) gets to rubber stamp the Council's selections, but that's really all they do.
Lest you think people might vote for heads of state, I'd just like to point out that only 33,973 people voted for Cameron in 2010. Just sayin'.
