And an excellent choice it is. If Catholicism has a future, it is in Latin America. Sadly, everyone from Mormons to Seventh Day Adventists, to plain old generic evangelicals have been successfully vying for those latino souls for quite a while now. But an Argentinian pope will sure as hell bring those souls back to the church of the saints!
And nobody needs or deserves a native born pope as much as Argentina does. I mean, Argentinians have refined the art of hero worship in a way that far surpasses the rest of the civilized world. The general population has (unofficially) canonized their favorite soccer player. And they are a forgiving people. Whenever he screws up, they think about their own sins, and forgive him.
And besides. It is such a great way for the church to thumb its nose at those British infidels for leaving the church so many centuries ago.
A win win for everyone.
