I was reading an analysis of Schonborn on an important Spanish blog yesterday, and the general feeling is that he is the most dangerous threat to the Pope because he masks his radicalism in moderate, conciliatory language (sort of like Obama). He is good at distancing himself from his more controversial positions.
In reality, he is opposed to virtually everything in the Pope’s vision even though his own diocese is a disaster, not only full of scandal and irregularities, but with a practicing Catholic population that grows smaller every day. Unfortunately, he is the youngest of the Cardinals, so even if Benedict lives for many years, Schonborn (who lobbied to try to get Martini elected pope last time around) will be young enough and political enough to be very influential in choosing his successor. And I’m sure Schonborn wants to be that successor.
Are you sure he lobbied for Cardinal Martini? Since he is a protege of Pope Benedict, and likely to find favor, I would think he would have supported Cardinal Ratzinger.
