Yiannis Ragoussis, the interior minister, spelled out what the prime minister meant. The decision on whether to call a general election will hinge on the outcome of 13 contests for the powerful post of periferiarch (regional governor), the first time in Greece that senior administrators have been directly elected. If Pasok candidates for periferiarch trail their conservative New Democracy rivals by a wide margin, the government will seek a new mandate.
Pasok supporters appear to be uncertain. Many say they will cast a blank ballot, or simply stay away on election day. Wage cuts for public-sector workers—Pasok’s core constituency—have angered party loyalists. But few are likely to switch to New Democracy, which ran the country between 2004 and 2009 and is blamed for running up the huge deficits that took Greece to the brink of bankruptcy.
