Egyptians vote in first free presidential vote Updated at 4:27 p.m. (CBS/AP) CAIRO - More than 15 months after autocratic leader Hosni Mubarak's ouster, Egyptians streamed to polling stations Wednesday to freely choose a president for the first time in generations. Waiting hours in line, some debated to the last minute over their vote in a historic election pitting old regime figures against ascending Islamists. CBS News correspondent Elizabeth Palmer reports from Cairo that voters of this country that has been ruled by pharaohs, kings and military dictatorships are excited to be choosing a democratically elected president. Election officials have set up elaborate checks in hopes of avoiding allegations of fraud. Monitors associated with former U.S. President Carter's organization are observing the vote, but by and large Egyptians seem to be having faith in the system. The choices in the race raised worries among many whether real democracy will emerge in Egypt. And the final result, likely to come only after a runoff next month, will only open a new chapter of political struggle. But in the lines at the polls, voters were palpably excited at the chance to decide their country's path in the vote, which is the fruit of last year's stunning popular revolt that overthew Mubarak after 29 years in power. For the past 60 years, Egypt's presidents running unchallenged have largely been re-affirmed in yes-or-no referendums that few bothered to vote in. Mohammed Salah, 26, emerged grinning from a poll station, fresh from casting his ballot. "Before, they used to take care of that for me," he said. Today, I am choosing for myself. Medhat Ibrahim, 58, who suffers from cancer, had tears in his eyes. "I might die in a matter of months, so I came for my children, so they can live," he said, waiting to vote in a poor Cairo district. We want to live better, like human beings. Adding to the drama, this election is up in the air. The reliability of polls is unsure, and four of the 13 candidates candidates have bounced around the top spots, leaving no clear single front-runner. None is likely to win outright in Wednesday and Thursday's balloting, so the top two vote-getters enter a run-off June 16-17, with the victor announced June 21. The two secular front-runners are both veterans of Mubarak's regime - former prime minister Ahmed Shafiq and former foreign minister Amr Moussa. The main Islamist contenders are Mohammed Morsi of the powerful Muslim Brotherhood and Abdel-Moneim Abolfotoh, a moderate Islamist whose inclusive platform has won him the support of some liberals, leftists and minority Christians. The debate went right up to the doorsteps of schools around the country where polls were set up. Some voters backed Mubarak-era veterans, believing they can bring stability after months of rising crime, a crumbling economy and bloody riots. Others were horrified by the thought, believing the "feloul" - or "remnants" of the regime - will keep Egypt locked in dictatorship and thwart democracy. Islamists, particularly the Muslim Brotherhood, saw their chance to lead a country where they were repressed for decades and to implement their version of Islamic law. Their critics recoiled, fearing theocracy. Some saw an alternative to both in a leftist candidate, Hamdeen Sabahi, who has claimed the mantle of Egypt's first president, the populist Gamal Abdel-Nasser. An Islamist victory, particularly by Morsi, will likely mean a greater emphasis on religion in government. His Muslim Brotherhood, which already dominates parliament, says it won't mimic Saudi Arabia and force women to wear veils or implement harsh punishments like amputations. But it says it does want to implement a more moderate version of Islamic law, which liberals fear will mean limitations on many rights. Many of the candidates have called for amendments in Egypt's 1979 peace treaty with Israel, which remains deeply unpopular. None is likely to dump it, but a victory by any of the Islamist or leftist candidates in the race could mean strained ties with Israel and a stronger stance in support of the Palestinians in the peace process. The candidates from the Mubarak's regime - and, ironically, the Brotherhood, which has already held multiple talks with U.S. officials - are most likely to maintain the alliance with the United States. A looming question is whether either side will accept victory by the other. Islamists have warned of new protests if Shafiq wins, which they say can only happen by fraud. Many are convinced the ruling military wants a victory by Shafiq, a former air force commander. Over my dead body will Shafiq or Moussa win. Why not just bring back Mubarak?" said Saleh Zeinhom, a merchant backing Abolfotoh. I'm certain we'll have a bloodbath after the elections cause the military council won't hand power to anyone but Shafiq. At left, watch Elizabeth Palmer go on the campaign trail with Amr Moussa for the "CBS Evening News" Shafiq was met by several dozen protesters screaming "down with the feloul" as he arrived to vote in an upscale neighborhood east of Cairo. Some protesters showed their contempt by holding up their shoes in his direction. Shafiq, who was Mubarak's last prime minister until he too was forced out of his post by protests, has been openly disparaging of the pro-democracy youth groups who led the anti-Mubarak uprising. Critics view him as too close to the generals who took over from Mubarak and whose own reputation is tainted by human rights abuses and authoritarian tendencies. But with his strongman image, he has appealed to Egyptians who crave stability and fear Islamists. The country is going under. We need a president that implements justice and brings back security. Bottom line," said Essam el-Khatib, a government employee voting in the Cairo suburb of Maadi. Nearby another man, Sayed Attiya, shouted, "What Shafiq? We didn't have a revolution to bring back Shafiq!
