For one, it would be his final mass before becoming pope. Might that pope be Cardinal Timothy dolan of new york . In the days leading to conclave, he has become a darling of the italian press. Or might that pope be Cardinal Omalley of boston, whose humble capuchin robes and leadership in the wake of the nationwide sexual abuse scandals have endeared him to his fellow electors . While neither claims to want the job thats just way too out of the realm of probability. I have bought a roundtrip ticket. So reporter their candidacies are a sign of a race that has no clear frontrunner. Cardinal omalley and Cardinal Dolan are already quite popular here in italy. Theres already a sort of fan clubs around the two of them. Reporter still the 28 italian cardinals represent by far, the biggest voting bloc by nationality. True to form, theyre thought to be pushing for an italian pope. But as the multitude of languages that we hear today, suggest on the eve of the conclave, vatican city is not italy. The worlds catholics are arriving to see the election of a new pope. For the first time, they may see that pope hail from latin or north america. Could that many Cardinal Scherer of brazil. Or Cardinal Ouellet of canada . Two candidates who work in the vatican. Looking for someone who has executive skills, someone who can talk about jesus with an mba. Reporter this is a historic election with the church at a crossroads, particularly in the United States. In fact, in a new abc News Washington post poll, an overwhelming number of catholics disapprove of the churchs handling of the sex abuse scandals. In addition to criticism shared worldwide of a corrupt vatican banking system. What is it that the church needs . Where does the church need to go . Reporter one thing is certain. The race is wide open, with all eyes on that chimney as rome awaits tomorrow. Of course no one can really predict who the pope will be, but whether it be a conservative, a reformer, an italian, a north american, latin american, african, one thing that all fangss can agree upon, according to the experts, is that age and stamina will be crucial factors come this election. So look for a pontiff in his 60s, young and spry enough to handle the grueling demands that this next pope will face. Thanks so much, josh. Theres something we want to show you. When those cardinals gather to choose an heir to st. Peter, theyll be standing above a sacred place, 40 feet beneath floor the dome behind me, theres a crypt inside a wall marked with the symbol of st. Peter. The bones of a man in his 60s when he died, and the pope declared them to be the bones of st. Peter, who was also crucified. And the dome above reaches toward the gates of heaven, where he is believed to be waiting with the keys. As the cardinals gather beneath. These princes on earth. Lets bring in cecilia vega with what they are going to do as the ancient process unfolds. Reporter one day before the doors to the Sistine Chapel are locked an oath of secrecy for the only people allowed in during the conclave. 90 people in all, doctors, nurses, waiters, swift guards, paving the way for 115 cardinals to select the next pope. Reporter is this daunting for some people . I think it frightens them. Some have told me its a scary moment because they dont want to make a mistake. Reporter the voting may begin right away up to four times a day until twothirds of the cardinals agree on a name. They write their choices on paper ballots. One at a time, they walk to the altar, and under the watchful eye of michelangelos last judgment, cast their votes. Three cardinals do the counting. Then those ballots are burned. Never to be seen again. Even in this modern world, it is a centuries old ritual that delivers the results. Black smoke means no decision, white there is a new pope. This is the black smoke right here. Yep. And this is the white. Reporter how do they do it . And Italian Special effects crew gave us a demonstration. Seems easy. Okay. Well see. Reporter so, i should stand back . Yeah, its really hot. Reporter turns out, creating smoke in the vatican is like creating smoke for movies. So no pope . No. Reporter not today . Maybe tomorrow. Reporter maybe tomorrow. The conclave used to burn wet straw to make black smoke. Today, it uses a mix of chemicals. But sometimes, even in the vatican, the plan fails. In 2005, the smoke wasnt black or white. It was both. In 1958, there was gray smoke. In 1978, it blew right back inside the Sistine Chapel and made the cardinals sick. Today, our smoke was bright white. All we were missing was a new pope. I can hear the crowds in st. Peters square cheering already. And so i have with me tonight, a sample ballot like the one that the cardinals will use tomorrow to vote. We know that many of them try to disguise the name of the pope that theyre choosing when they write on it, so that no one knows who theyre voting for. Sit a secret. They fold it once and then again and then it gets burned so that no one sees this vote. Skast that ballot, no one can see the name on that line. Secrecy of utmost importance. Its all in secret. Something very moving about a piece of paper in this very moernd and hightech world. So small. Thank you, cecilia. One of the men in the Sistine Chapel voting will be Cardinal Napier from south africa. Today i asked the cardinal about the true possibility of an american pope, and also what its really like inside that room. We always talk about the fact that its beneath michael angelo. Is there one part of that painting that you always focus on when youre sitting there . Indeed. I was sitting on the right on friday as you look up to that painting where the devils are pulling people down into hell. Thats what i keep in my mind. If im voting for the wrong person thats what the devil is preparing for me as well. So here we are the night before you move into the dormitory. Is there something that you do the night before when youre packing your things to take there . I have to remember what not to leave behind. Its one of main ones. Weve seen the rooms. Theyre modest rooms. Some of them are quite nice. When you go in, they break a seal to make sure no ones tampered with it. The windows are also sealed . The shutters on the windows are sealed, so that no interference from outside or no signaling from inside to the outside can be done. This is just a mischievous question. Which is more likely, an american pope or an african pope . I dont think either. At the moment, i dont think either. The moment that you have that piece of paper and you fold it, is that the weightiest moment, the moment when you actually submit the name . This is the most solemn moment for me. I call on the lord jesus to be my judge to witness that i am voting for the one that i consider to be worthy. So that for me is the most solemn moment. Our thanks to Cardinal Napier and a reminder that our team will be right here covering it all live tomorrow at 11 30 a. M. Eastern time. Please join us as the conclave begins. Now we turn to another big stories around the world. Starting with an attack in afghanistan. An afghan officer firing on american troops, killing two and injuring nearly a dozen more after a gunfight. It happened just after the American Defense secretary paid a visit to the wartorn nation. Martha raddatz has the details. Reporter the attacks have been unrelenting a suicide bomb in kabul this weekend, an attack at a military base on friday. And today, the deadly machine gun assault by an Afghan Police officer claiming the lives of those two americans. The attack happened just outside this village in wardak province where we once patrolled with u. S. Soldiers. Last year, 35 americans were killed in 46 attacks by afghan forces. But today u. S. Forces shot and killed two afghan civilians who drove too close to a u. S. Convoy. A u. S. Major was caught berating one of his soldiers after the shooting. All of these incidents are taking a toll. It definitely does start to affect the trust of both sides working together. Its a simple as that. Reporter the violence cast a very big shadow on the first visit of the new secretary of defense, chuck hagel, as did the stunning comments from afghan President Hamid karzai. Karzai claimed that the u. S. And the taliban were, in effect, working together to destabilize his country, an accusation that outraged many in the u. S. And shows that transitioning out of afghanistan is no easy task. Martha raddatz, abc news, washington. And now we have a program note. Tomorrow George Stephanopoulos will sit down with president obama at the white house and well bring you the details tomorrow night right here on world news, and also the next morning on gma. Some consumer news back at home tonight, the ban on the sale of those giant, sugary sodas, the subject of so much late night comedy, that ban has been put on hold. It was a Big Public Health effort by the mayor of new york to help with obesity. It was supposed to start tomorrow, but today a judge says, not so fast. Abcs gio benitez tells us why. Reporter today, on the eve of the nations first ban on large sugary drinks, new yorkers were bracing for change. One of the last ones. Enjoy it, because its the last day. Reporter and businesses were ready. Dunkin donuts wouldnt given you would have given you the syrup separately, and you would have had to pour it in yourself. Now a stunning reversal. A state judge striking down that ban on sugary drinks larger than 16 ounces. One of the more controversial policies in the battle against obesity. Im gonna take a little swig out of a comically oversized Movie Theater beverage, its so hot. Reporter mayor bloomberg made the ban a health crew said. In one 16 ounce glass of soda, youll find the equivalent of 27 cubes of sugar. In 51 ounces, 86 cubes. But the judge found the law would be unfair because it would apply to restaurants but not convenience stores, and would exclude other beverages that have significantly higher concentrations of sugar, like many lattes. I have to defend my children and you and everybody else and do whats right to save lives. Obesity kills. Reporter mayor bloomberg will appeal. Gio benitez, abc news, new york.

Do any of you take aspirin to prevent Heart Disease . Yes. Reporter what would you say if i told you it might help prevent skin cancer too . Oh, thats better, right . Reporter yeah the new Stanford University study, the largest of its kind, looked at 60,000 older caucasian women. Theyre the most likely to get melanoma, the deadliest form of skin cancer. Those who took aspirin at least twice a week had a 20 lower risk of developing melanoma. Women who took an aspirin for five years or more . The risk was down 30 . Researchers believe aspirin may kill cancer cells and even stop new ones from forming.
