To put this in context, I live in New Jersey. I understand the concerns about security with email voting. Though I think the bigger issue will be the lack of power and access to polling stations. Even though power has been restored to the majority of households there are still ~500,000 households without power. Who knows how many polling stations have been affected. In addition many areas have curfews and limited access either because of downed lines, blocked roads, and or flooding. Even with all this I have a feeling few people will be voting via email. I think NJ is just trying to give people as many options as possible because of how large of an impact this storm has had.
