Yes, some on the Catholic right, especially the far right, are attracted to far right populists.  This is why Pope Francis should be clear about the fact that movements like the National Front are incompatible with the Catholic faith.  I hope that at the very least Pope Francis will put out an encyclical on populism.

And Pope Francis' non-answer on the French election was odd.  I guess that popes shouldn't be butting into elections however and Francis didn't want to get into an argument with Le Pen.
