only "ex cathedra" pronouncements from the Pope can compel obedience.

You don't agree with Lumen Gentium then:

"This loyal submission of the will and intellect must be given, in a special way, to the authentic teaching authority [magisterium] of the Roman Pontiff, even when he does not speak ex cathedra in such wise, indeed, that his supreme teaching authority be acknowledged with respect, and that one sincerely adhere to decisions made by him, conformably with his manifest mind and intention, which is made known principally either (1) by the character of the documents in question, or (2) by the frequency with which a certain doctrine is proposed, or (3) by the manner in which the doctrine is formulated."

The passage you provided deals with the Pope and the Magisterium - of which Mahoney is A PART - but Mahoney does not fully represent the Magisterium - nor does he alone decide the teaching.
Mahoney is not representing Church teaching here...he is just acting like a typical liberal....which he is.
The Church has a wide spectrum of bishops and cardinals in the Magisterium...many of whom would disagree with Mahoney.

I may be off base on the various pronouncements from the Pope, and am willing to reconsider that part over time, but I still don't think I'm required to adhere to the POLITICAL pronouncements of a Bishop.

One, Mahony is not the Pope. Two, the immigration issue is not a religious one, so Mahony's opinion is not binding to any extent on Catholics.
