Let's cut to the chase: There is really no such thing as a "liberal" in the Catholic Church heirarchy, because the modern political ideas of liberalism and conservatism don't really apply to these matters. There is not one Cardinal who is going to push for the church to drop its opposition to abortion or to allow priests to marry or to allow female priests or anything in that manner. There are those who are more doctrinally liberal and those who are more doctrinally conservative.
And - in a counter-intuitive development - the younger leaders are more conservative than the older leaders. The older leaders still have a large stake in Vatican II whereas the younger leaders want to pull a lot of those reforms back.

It's an interesting read, though the first chapter is melodramatic nonsense.
There is a big push in the Church to bring back lapsed Catholics into the fold. I'm not going to actually confirm these numbers, but one of the leaders of this movement at my old parish said that that if Lapsed Catholic was a religious denomination, it would be the second largest denomination in the country. Keep in mind that the Catholics are counting everyone who was born and raised a Catholic and does not attend mass today in these numbers. So, if you were raised Catholic and converted to Baptist, you are still in the group.
There is a very strong belief in the church that part of the reason that there are so many ex-Catholics is because of Vatican II.
There is a war coming in the Catholic Church and the reformists are going to be routed. I suspect that part of the reason Benedict is leaving is because he is too old to deal with this issue now. I think he was originally selected as a compromise candidate - the most Conservative member of the Old Guard and someone who was extremely close to JPII. It's entirely possible that a lot of people - including Benedict himself - are surprised that he is still alive and don't want a placeholder any longer.
The Vatican has already fired its first shots in this war - shockingly at nuns, who do tend to be fairly liberal, believe it or not.
