Only McCormac and O'Brien have said what they think about admitting married men to the priesthood. You can certainly guess that a majority of the American cardinals favor it (though they would never say so), and "pragmatists" like Tettamanzi and Scola might also be open to the idea.
The stark reality is staring them in the face.
"I'd bet that JPII was not in favor of the Anglican dispensation initially, but he was brought around to it as a way to 1)accommodate the Anglicans who wanted to jump the fence and 2) add some small number of priests."
Cardinal Hume was very much in favour of it and prevailed on him to allow it - he still (unlike our current crop of bishops) had visions of re-converting England.
However, most of the UK bishops were against it on the grounds that it would create 2 classes of married men in the Church, with only the select minority being eligible for ordination. They would only have favoured it if it was opened to all Catholic men - not just former Anglican clergy.
I doubt Tettamanzi would favour it as he seems to have a thing going for the homosexuals, and Scola is quite conservative in some respects.
People like Daneels, Kasper and Lehmann might, but they are even more liberal than JPII and would destroy the Church in many ways.
