In my opinion the entire Iowa fiasco happened because Democrats were manipulating the votes to ensure Bernie wouldn't win.
The failure of the app brought unwelcome scrutiny to the process. For three weeks now they've been trying to find a way to reconcile the real numbers with the manipulated numbers.
They got caught cheating and they're still trying to cover their tracks.
New Hampshire and Nevada intensified the scrutiny of the process and with everyone watching they couldn't even attempt to manipulate the count.
Iowa proved Democrats are manipulating the numbers and now that they were caught they can't risk being caught again.
The Democratic leadership has lost their power to control the outcome and they're in full panic mode.
