Here's one of the best examples of the total departure of the EU institutions from the normal democratic constraints on their mandate vis-a-vis national affairs:

For a reply:
That is correct (assuming the reported call did take place): the ECB represents a sub-section of the executive pillar of power in the EU (and via the national central banks - in the member states), just as the US Fed. Neither the Fed nor the ECB have any business in influencing or restricting the legislative pillar (in the case of the above incident - the electoral process) or the entire executive pillar (in the above case - pertaining to the Presidency to which monetary policy institutions are accountable or co-accountable whenever oversight over monetary policy institutions co-rests with legislature) or the judiciary (presumably, Mr Draghi might call on European or national judges too, should their workings approach the issues related to OMT or other aspects of the monetary policy).
To see this, simply replace ECB's Draghi with, say, General X of the Common Security & Defence Policy calling President Napolitano to express concerns about Italian elections. How fast will 'military interference in political affairs' rise to media headlines?
Europe is now clearly on a dangerous path that can lead to subversion or manipulation of democratic institutions and processes.
