Perhaps I'm reading more into the quote by Giuliani than most; but I don't think he's being considered or taking the SOS position as it my pose a conflict of interest down the road. I find what he stated very interesting:
"Before I joined the campaign I was very involved and fulfilled by my work with my law firm and consulting firm, and I will continue that work with even more enthusiasm." "From the vantage point of the private sector, I look forward to helping the President-elect in any way he deems necessary and appropriate."
