Wow. First, let me say, I usually don't bother reading non-magical AUs because I basically never like them. But MAN am I glad I read this! Fantastic!
I LOVE this Snape. The Neo-Nazi backstory works really well and the Allen Dore part-- genius! Sheer genius. And I really liked your Harry here...
And, yeah, the 'inexplicable connection' is a cliche and the dramatic press conference declaration of love is too-- but somehow you actually made it charming instead of icky, so somehow I even liked that.
