With No Front-runner in Sight, Outcome of Papal Conclave Is Anybody's Guess

As 115 cardinals prepare to lock themselves into the Sistine Chapel until the longed-for white smoke signals the election of a new pope, speculation over the leading candidates mounts.

VATICAN CITY - One hundred and fifteen cardinals will proceed Tuesday into the Sistine Chapel and take a vow not to reveal any detail from the conclave. They will hear a meditation from one of the elder cardinals, who is not voting because of his age, over eighty, and will sit down to write, on paper, the name of their preferred next pope.
