The Commission is the governments of the member states.
Which makes it ironically the most corrupt and undemocratic part of the EU, despite being literally made of people elected through national elections. People who say member states are more democratic than the EU tend to have a problem with this one.
Hum, the governments of the member states convene in the European Council, actually. (The Commission is more like a civil servants organisation, second rank to this and in delicate balance with the European Parliament.)
