This is the way I see it as well. I don't believe economic conservatives are really happy about this choice, but most are trying to put a happy face on anyway. Argentina has an awful economic history - filled with currency defaults. They've had way too much "social justice" and they never, ever learn that government confiscation and collectivism doesn't work. This pope seems to be very conservative on the social issues and that is good news, but I don't feel very reassured about his economic views. Hopefully it turns out that he understands that free markets lift people out of poverty, not government dependency.
He supposedly isn’t popular with the Vatican Curia
Maybe he can clean up the Lavender Gay Mafia mess within the Church.
I would consider him an outsider. That is what they need.
