Ireland today holds the European Union’s only popular vote on the controversial Lisbon Treaty, which would strengthen and streamline the EU, among other things creating an EU president. The union’s other 26 members will consider ratification in their legislatures. Polls show the Irish vote as too close to call. A “no” vote would derail the treaty, and could hit the euro. The Lisbon Treaty is the successor to the stymied European Constitution. (MarketWatch)
