Raffo was interviewed to keep Polk at bay during the process. That apparently didn't even work. It just seems to me, when you look at Raffo versus the names that were tossed around, that one of these things is not like the other ones.
It's quite obvious the program was mired in a power struggle and the nepotism wasn't just rampant, it was being flaunted in Byrne's face. That **** had to end, and that meant Raffo was not a real candidate.
