For reasons that are now obscure, there is an unwritten rule that Commission presidents must be drawn from the ranks of past or current prime ministers. This has in large part accounted for Barroso’s high hopes of getting a second term.
由于并不明显的原因，委员会主席必须从现任或者前任总理之中产生，这已经成为不定之规。这也是巴罗索很有希望获得第二个任期的原因。好像没有其他可靠的候选人对他提出挑战。
