Sanders went up against the greatest, most rigged political machine since Tammany Hall with no major donors, no major endorsements and (at least at 1st) almost no name recognition and showed himself her equal.
This was a Sanders victory hands down and even the Clinton owned media is saying it. I'm not criticizing Clinton, spin is a huge part of the game but facts are facts. She'd be in okay shape had she not jumped the gun and claimed victory. Doing so 40 minutes before the Dems said, "Oops, we counted Clinton supporters more than once. Sanders is actually in the same place" didn't help her either. NV will decide this I think and I think Sanders will have the better strategy there.
