Poll: Approval of ND's Obama invite inversely proportional to Mass attendance

Props to the Pew Forum for taking up this issue (my underlining):

Most Catholics who have heard about the issue support the University of Notre Dame's decision to invite President Barack Obama to speak and receive an honorary degree at its May 17 commencement, even though he supports abortion rights and embryonic stem cell research. But a new poll conducted by the Pew Research Center's Forum on Religion & Public Life also finds a deep division on this issue between the most-observant Catholics and those who are less observant, as defined by frequency of worship service attendance.

"...Regular church attenders also express much higher levels of disapproval of Obama's visit to Notre Dame. Among white Catholics who attend church at least once a week, a plurality (45%) say it was wrong for Notre Dame to invite Obama, while the majority of less-observant Catholics (56%) take the opposite view, saying Notre Dame was right to invite him."

Now, of course, weekly Mass attendance (i.e., Sunday Mass attendance) is compulsory for Catholics. That means people who don't attend Sunday Mass aren't even practicing the basics of their faith. Catholics who are maintaining the minimum standards of living their Catholic faith disapprove of the decision (as a plurality).

Isn't it odd that Fr. Jenkin's invitation corresponds more with Catholics who are not going to Mass on Sunday on a regular basis than those who are? Isn't it strange that Catholics who don't make it a priority to receive Jesus are fine with Notre Dame making it a priority to receive Obama? And finally, why can almost 1 in 4 Catholics who don't even attend Sunday Mass regularly see something wrong with an invitation that the supposed flag-ship of American Catholic education is blind to?
