The idea that European elections should be uplifted from their status as secondary elections by means of actual European campaigns has been floating around quite a while, and for all we know we are supposed to get candidates for the next President of the Commission campaigning for our votes for their family of parties. This makes sense, as the Lisbon Treaty defines that the European Parliament does no longer just approve the Commission President, but elects him, meaning he will likely be provided by the largest parliamentary group. This makes him just as democratically legitimised as the head of government of many member states. This includes for example the German chancellor.
Strangely, today I had to read that Chancellor Merkel does not approve of the process analogous to the one that got her elected two (soon to be three) times.
