GW,
I've no idea about his stand or lack of it on offshore drilling, only know what I have heard from what others have said here.
As to class size, I have listened to several radio and TV discussions of this, and my understanding is not that he wants to increase class size. He, and a number of principals, want to be able to continue to use a whole-school average to achieve the proper class size, rather than having an absolute max number for every single classroom.
I understand why. If you're operating on the absolute no-more-than-___ students in a class for such and such a grade, the logistics can be nightmarish under all kinds of common situations. Say you have 2-3 full Algebra classes (or whatever) and you get a new student transferring to the school in, say, February. With individual classroom absolute maximum rules in place, you have to hire a teacher mid-year, and find another classroom and divide up the 3 other classes so some students from each class will become part of the 4th Algebra class. This is disruptive to all the students and teachers.
If, however, you can use whole-school averaging to achieve class size, and you have the full Algebra classes, but you have several other classes that aren't full, you don't have to disrupt all your Algebra students and teachers mid-year for a transferring student.
There are plenty of other situations where the averaging makes more sense. Not a perfect system, as there will always be some classes with more than the ideal # of students, but logistically and administratively, as well as common sensically (is that a word), the averaging seems more practical and doable.
