The United States is the home country of 10 of the 133 cardinals eligible to vote for the next pope of the Catholic Church. That's more than any nation except Italy, home to 17 of the electors who will gather at the Vatican's Sistine Chapel on Wednesday for the conclave that will choose a successor to Pope Francis.

While there are a few cardinals seen as front-runners to succeed Pope Francis -- two often mentioned are Italian Cardinal Pietro Parolin and Filipino Cardinal Luis Antonio Tagle -- many of the clerics who will vote have not made up their minds.
