The European Union is a polity in the making, where political actors conten
d about basic questions of governance. While students have begun to map con
tention between public parties and private interests, little attention has
been paid to how office-holders in the Commission conceive of European inte
gration. Using interview data collected from 140 senior officials of the Co
mmission, I identify contention along four dimensions: whether the EU shoul
d have supranational or intergovernmental institutions; whether it should u
se democratic or technocratic decision making; whether it should promote re
gulated capitalism or marker liberalism; and whether the elite should defen
d the European public good or be responsive to various interests. My findin
gs challenge EU theories that conceive of the Commission as a unitary actor
with a pro-integration agenda.
