What if a US politician showed the same kind of reform as Pope Francis?

9. The pope can order up any reform he wants

A president can't: there's a little thing called Congress, not to mention the Supreme Court. Our Constitution metes out certain jobs to each of these powers, and one may block the actions of another.

In other words, the president is not the pope.

Papal supremacy refers to the doctrine of the Roman Catholic Church that the pope, by reason of his office as Vicar of Christ and as pastor of the entire Christian Church, has full, supreme, and universal power over the whole Church, a power which he can always exercise unhindered: that, in brief, "the Pope enjoys, by divine institution, supreme, full, immediate, and universal power in the care of souls."
