To date, the only study on outcomes has been positive for prescribing psychologists in the DoD.

I have to say that I am skeptical of the AMA's fight against this due to "patient safety." I think it has more to do with protecting their self-appointed turf and money.
Ok, point received. Very select sample, of course, but the premise makes sense. A key quote from the first link was in Findings summary, point 2, where they subjects "knew when, where, and how to consult." That, combined with stringent standards of training, as you mention below, makes more sense.
I believe the wording of the bill mentions that the supervisor has to be a psychiatrist, or a prescribing psych who has passed board approval. Granted, I would also argue for fairly stringent standards of training. But, the opposition to Rx privileges has generally not stuck on training practices, but rather the concept in general.
Also, you are assuming that that the MD paradigm is without error?

And no, of course, I'm not suggesting that anyone is without error, MDs included
The reason I opted out of pre-med years ago was that the medical profession seemed more of an industry than anything else to me; I believed that, after training for years within that industry (funded by pharma interests, and staffed by relatively bright-eyed youngsters like my former self), I would have had a harder time keeping sight of my initial interests in the profession. That's a much bigger issue than simple human error, of course, that's a seismic fault within the paradigm. The stakes are just tremendously high with patient w0rk, however; hence, your suggestion of training standards. Then, at least, poor judgement and inexperience can be mostly controlled for.
Personally, given that 70% of psychotropics are prescribed by PCPs (your NAMI link, above), it makes much more sense for psychologists to have a more active role in an area in which they are expert. With the coming age of medical record integration (I know it's harder for paper-based practitioners to grasp; it's a slow transition), one would hope that patients would have greater ability and safety in conferring with, and being referred to, whichever expert most suited their needs. With that, again there exists the hope that each expert could access the patient's record and be properly trained to accurately assess whether or not This Anti-Depressant (let's not get into the over-use of those... another interesting thread lately) reacts with That Anti-Hypertensive or The Other Grapefruit Seed Extract the Pt is taking for their eczema.
