Cardinals failed again Thursday morning to find a successor to Pope Francis, sending black smoke billowing up through the Sistine Chapel chimney after two more inconclusive rounds of conclave voting.

The cardinals are shut off from the world for the secretive voting that will result in new leadership for the world's 1.4 billion Roman Catholics.

As cardinals gather at the Sistine Chapel to vote for a successor to Pope Francis, there is no single frontrunner, and it remains unclear whether the new pope will align with Francis’s more inclusive ideology.
