My take is that Debbie wasn't the prime mover. Someone high up in the party... HRC, Obama, whomever ... said that "Awan is one of our friends, take care of him."
So it was said, so it was done.
We don't know who gave the order, or why.
I don't believe young Awan "won" the lottery by chance. His lottery slot was "won" by the Pakistani ISI, and he was selected to work on their behalf. Only, he was such an enterprising low-life criminal that he got in unnecessary trouble.
The dumb a-hole Wasserman Schulz (and she IS dumber than a bag of hammers) has probably realized at some point in the last year or so that she is going to be holding the bag on THIS particular Democrat scandal.
Good.
