Yes he did, and bemoans the fact in the course of the speech.
In the Catholic Church, unlike for example the Episcopal Church where such matters depend on a show at hands at a triennial Convention, truth is not determined by majority opinion.
In fact, often enough, when you have a majority of “the world” agreeing with you, it’s an indication that you’ve strayed from the truth.
Example: After the discourse on the Bread of Life, the majority OF DISCIPLES rejected the teaching of Christ’s presence in the Eucharist “and walked with him no more” (John 6:66). And when Pilate presented Jesus to the crowd at his Passion, the majority opted for Barabbas.
“All may / some do / none must” may be the doctrinal criterion of some denominations, but not of Roman Catholicism.
MSNBC or gallup (CNN) poll? Rasmussen poll doesn’t agree.
Catholics, because of a strong cultural identity, tend to identify themselves as Catholic even if they haven't been to mass since they were kids. Those people are lumped in with the practicing Catholics in order to arrive at that number. Obama's support among weekly mass attenders was much smaller.
The Church lost a lot of people during the 70's and 80's, due to the haphazard Vatican II reforms and the poor teaching of the children during those years. As a convert, I was shocked that some of the things I knew about the Church and her teachings was unknown to cradle Catholics in my own parish.
Thankfully, things are beginning to turn around, but the Barque of Peter is a large ship, which turns slowly. It will probably be another 10 years before things are really squared away. The Holy Gather is a true blessing to us, and may he live long years more and confound those who want to wreck the Church.
67% is not really the flock. These are nominal Catholics who claim to be ‘Catholic’, but don’t attend Mass and couldn’t tell you much about the Catholic Faith if their life depended upon it (at least nothing accurate).
