welcome back to weekends with alex witt, let s go over to vatican city where 115 cardinals are getting ready to vote on a thu pope. an incredible image for you today as a worker installing a chimney stack on the roof of the sistine chapel. white smoke will rise from that chimney stack once the cardinals choose the new pope. between now and tuesday when the conclave begins, what do the cardinals have in store for them? well, alex, tomorrow is really the only day off if you may call it that way for the cardinals. because on monday morning, they will still meet once again and for one last time in the general congregation of cardinals and then, of course, on tuesday morning before the start of the election and the conclave they will hold mass in st. peters
