As always, Europeans reject EU transnationalism whenever they are given the chance to vote on it. (Via Instapundit.) Having learned from the past, no other EU nation allowed a public vote on the Lisbon treaty, but Ireland’s constitution requires one.
UPDATE: The vote was 53%-47%, similar to when they rejected the Nice treaty 54%-46% in 2001. That time they made a highly controversial second attempt a year later in which the treaty passed.
