Catholics should have a new pope next week. Church cardinals who already are gathered at the Vatican decided today to begin voting on Tuesday, reports CNN. As per tradition, they will vote in the Sistine Chapel and send up black smoke after a failed ballot (a candidate needs two-thirds of the votes, plus one extra) and white smoke when they've got a winner. So will it be the 68-year-old Canadian, or maybe the 64-year-old from Ghana? Slate runs down a short list here. (More Vatican stories.)
