Obama increasingly finds an ally in Pope Francis

But in the long term, analysts say, Democrats may pay something of a political price.

To soothe American Catholics, who may have grown suspicious of the church’s partnership with a liberal White House, the pope in the coming months and years is likely to zero in on fundamental disagreements with the Democratic Party on issues such as abortion and religious liberty, said Joseph Prud’homme, a political science professor and the director of the Institute for the Study of Religion, Politics, and Culture at Washington College.

“I believe Francis will remind the faithful in his position as supreme pastor about what he has consistently said about life and religious liberty. I hope, and I expect, that he will, after these initiatives [on Cuba and climate change], remind the faithful of the unending position of the church with respect to the sanctity of human life, the importance of religious liberty,” Mr. Prud’homme said.

He added that Francis could create a deeper, almost irreparable rift between the church and the Democratic Party and create further headaches for liberal Catholics in electoral politics unless the Democratic Party “changes and recalibrates its center of gravity away from these issues which, from the position of the church, represent grave and serious moral error.”
