By Egyptians living abroad comes a day after two election front-runners, one of Mubarak's former foreign ministers and a moderate Islamist, squared off in the Arab world's first ever presidential debate. The two traded barbs over the role of religion and how to bring democratic reform to Egypt.. Viewers crowded around television sets in outdoor cafes for the debate, aired Thursday evening on several independent TV channels -- a new experiment for Egypt after nearly 30 years of authoritarian rule under Mubarak, forced out of power last year after a wave of protests.. For most of Mubarak's rule, he was re-elected in referendums in which he was the only candidate. The last presidential election, in 2005, was the first to allow multiple candidates, but Mubarak was considered a certain winner and campaigning was weak -- and a direct debate was out of the question.. The debate pitted Amr Moussa, who served as Mubarak's foreign minister for 10 years until becoming head of the Arab League in 2001, against Abdel-Moneim Abolfotoh, a moderate Islamist who broke with the Muslim Brotherhood last year. The two are among 13 candidates competing in the election, due to begin in Egypt on May 23. -- AP
