“It’s starting, I really think it does.  I hear my brother cardinals say this. A week ago, we would have said, Wow, we’ve got a lot of work to do but now you see a sense of resignation and trust and faith.”

There has been speculation that Dolan could emerge as a “dark horse” if there’s no consensus among the cardinals in the first few rounds of voting.

Dolan says he’s planning to go back to New York.

The names of Italians, a Brazilian, even a cardinal from the Philippines  have been mentioned as possible popes, but it’s all speculation and we won’t really know until the white smoke comes form the chimney at the Sistine Chapel, the bells of St. Peter’s peel.
