After reformist candidates were wiped from the ballots, Iranian voters chose yesterday whether to send a stronger message by voting or by staying home: The reformist movement urged Iranians to boycott the election after more than 2,000 of their candidates, including 87 deputies in the 290-seat body, were disqualified from running by a watchdog council controlled by the hard-liners. But conservatives urged people to vote, suggesting as they have for much of the past 25 years that a huge turnout would sting the enemies of the Islamic revolution. "The turnout will indicate whether people are giving their approval to this regime or not," said Abbas Amanat, a history professor and the director of the Middle East Center at Yale University. "If the turnout is low, it is an obvious sign of frustration." No results were released Friday. State-run radio and television said polls were kept open for an extra four hours because there had been such a high turnout among the 46 million eligible voters. That happens in virtually every Iranian election, however, and it was possible to find evidence that neither side had entirely succeeded. Polling stations were far less crowded than during the previous parliamentary and presidential elections, which saw major victories for those promising greater social freedom and less autocratic rule. While vegetable markets in northern Tehran and the ski slopes were packed, the polling stations were doing a slow trade, witnesses said.
