So who's shenanigans?

for the rest of their natural lives.
I do believe that bureaucracies of all kinds are inefficient and often ham-handed.
New York should investigate, find what happened, and fix it.
That is how things are made better.

• Death (pretty obvious)
• Moving and not updating your voter registration
• Not voting in a couple of consecutive elections

Where I live now, the registrar of voters sends a card with my voter information to my address a couple of months before every primary or general election. If that card gets returned, I believe my record would get marked bad address.

In a state I used to live, if I didn't vote in a couple of general or primary elections in a row I would get marked inactive (I think the count was 3).

Whenever they finally get around to purging the rolls, anyone that is marked dead, bad address or inactive would get purged and for a valid reason. I don't know how often they purge, but when they do, I would have to suspect a good percentage does get dropped.

In Chicago, where I vote, I don't have any problems. However I make a point of voting in every possible election that goes by. Which probably keeps me fresh and up to date on the rolls. Cook County BoE sends me a little card every election year telling me my polling place and other information so I know I'm good.

I think Bernie has energized a lot of first timers or others who've sat on the sidelines for a while and now are rushing to take part, which is exposing all kinds of problems with the rolls and our patchwork primary process. I also think that with emotions running so high, Bernie is so much closer than anybody ever dreamed, that makes people reactionary and likely to believe whatever idea feeds their emotional state. Hence so many people accusing Hillary of our right election theft when there's no proof, nor even a good rumor of it at all.
