Will the widely expected — though not certain — rise of a nationalist party in Germany’s Sunday election deprive the European Union of its largest economy? Will the Alternative for Germany party’s advocacy of exiting the EU, an idea popularly known as Dexit, eventually cause the Union to collapse?

For now, officials at Brussels are putting on a brave face. They cite Brexit, as the British referendum to leave the EU was known, as an example of the likely economic downturn for any country leaving the EU. Yet, Germany’s AfD, which is widely predicted to emerge as Germany’s second largest party in Sunday’s national election, is rooted in part in hostility to the EU.
