I think Catholicism has much bigger problems in the US then evangelicals gaining tracking.
Like people which by the Wikipedia definition of fascist being fascist using Catholicism as a tool to push their believes which are not at all compatible with the current world view represented by the Church in Rome.
A Pope which is able to say "I denounce ... as unchristian and un-american" which isn't some random person in Rome but someone seen as an American is kinda useful if you want to reduce the reach of such influences.
