Cardinals are returning to the Sistine Chapel to continue voting for a new pope. The first conclave ballot failed to find a winner, sending black smoke through the chapel chimney. Some cardinals expected a short conclave to replace Pope Francis, but it may take a few rounds of voting for one man to secure the two-thirds majority needed. The secretive ritual began Wednesday with Cardinal Pietro Parolin leading the proceedings. Thousands gathered in St. Peter’s Square to watch the event on video screens. The cardinals are sequestered from the outside world until they find a new pope.
