I just read why 64 Bernie NV delegates had their credentials stripped--and I shed a tear or two

114. Personally, I think the key factor is the DMV.

That is the most likely way voter registration is being changed. And it would have to happen only when that voter renewed or updated their drivers license. And only in states that have party affiliation included with voter registration.

It wouldn't necessarily be the voter's fault either. Filling out a paper form once every several years would make it difficult to know what is expected. If the DMV person is completing the form for the person then they might forget to ask the question. Especially if it is a new employee.

The software application used by the DMV may have a poor design. For instance it might not include confirmation that a person does not want to register to vote or identify their party affiliation. In at least one state if party affiliation is not checked the default is "no party affiliation". The default should instead be "do not change".

The other issue that might be present is it is likely that voter registration data may not be kept by the DMV once it is transmitted to the voter registration office. I would be hesitant in changing this aspect of it. But keeping the fact they are a registered voter should be sufficient.
