"We don't have many orthodoxy issues in Philly"
This is true because Philly has consistently had orthodox bishops in the years during and following Vatican II to this day. Cardinal Krol, Bevilacqua, and now Rigali have all been awesome shepherds.
Unfortunately, it is the rare diocese today that claim such a consistent Orthodoxy. Most dioceses were put under the charge of hard or soft liberals following Vatican II, during which time most of the damages were done, and then the bishops which followed those liberals tended to be either status-quo (those who stop any more damage from happening) or milder liberals who slow down the damage. Recently, however, the trend has been improving.
I don't know much about the DC Diocese. Frankly, I am more concerned in who replaces Card. Keeler (turned 75 two months ago) in Baltimore, a major diocese that, in my view, has followed the typical pattern I noted above, and now needs an overhaul with a staunchly orthodox bishop.
I have a friend from Balitmore whose Catholicism is, shall we say, a little different from that of the Faith of the Ages. Whenever I used to comment on some bizarre understanding of hers, she would shrug and say, "hey, I'm a Baltimore Catholic." It sounds to me as if they need a bishop who could bring them out of bondage in Baltimore and back to the Church Universal!
Rumors aren't worth much ... last week I heard a rumor that Myers was going to replace McCarrick. Maybe he will replace Keeler, instead.
