Thanks for the feedback, folks.
Yes, I was not going to be accepted to upper tier schools because my undergraduate GPA was horrific ( I was a graduating senior for 4 semesters!), even if it was 20 years past.
I won't argue against "the way things are"; if PhD programs won't accept South as my Master's, then I'll have to start over once I get into a program. This is my "second career" and I'm not in dire financial straits. I was hoping to use the work at South as a stepping stone into a mid or higher tier program.
Having said that, I have found the time spent at South rewarding. I have learned and I have been pushed. I have compared some of my courses against the syllabi of other graduate courses and found them to be equitable. Of course, the key point would be grading...if South just hands out grades for payment, then of course the degree is worthless. I have felt in a couple of cases I did get a higher grade than I deserved for some of my coursework. The counter to this is that if I have read these (and other) boards correctly, this is common through the soft sciences in graduate work.
Again, I am not arguing that South SHOULD be accepted; simply sharing my experience there.
So, returning to the original question: I have had some feedback though other sources (LinkedIn, etc), and it seems that my area of interest lies in the intersection of the criminal justice, political science, and public policy fields. I have started looking at published papers to see if there is work being done in my interest, and I will research those doctors and those programs. If anyone has a recommendation along those lines, I'd be glad to hear it!
If it helps, my thesis is exploring the possible differences in FBI COINTELPRO operations against the Klan and against the New Left which may have been caused by politics.
