They were lifelong Democrats who were shocked to discover they're been purged from the rolls just in time to be unable to vote in the 2016 primary.
You have no grasp of the facts because you run your mouth instead of actually digging for the truth.
You're the worst kind of false intellectual; just like flat earthers, you decide your conclusions ahead of time and then only look for evidence that supports them. All else is discarded.
The stench of intellectual dishonesty oozes from nearly every one of your posts.
What is the election official supposed to do on election day when a voter isn't on the roll? According to their rolls, the person isn't a Democrat. Yes, you are right, people were purged from the rolls without their knowledge and that's not right. In fact it was illegal. It's also a fact that New York is plagued with elections issues just like Florida is. I don't know why the people of that state don't demand this shit be stopped. Maybe the settlement arrived at last year and signed off on this year will begin this process.
There has been no official explanation of what happened other than the admission of guilt that 200,000 voters in New York were illegally purged from the rolls. So, neither you nor I can really know what happened. But I'll go with you on this. As you and others say, skullduggery took place in three districts in New York that skewed those districts to Clinton. Those districts were Brooklyn, Queens and Manhattan. Is it your claim that those three districts is why Sanders lost the Democratic Primary?
Some simple arithmetic will prove you wrong if that's what you are saying. Sanders' campaign was the walking dead before the New York primary even took place.
