Don't think we should have to legislate for how registrars use ALL available information to preserve the integrity of elections - especially where there are so many individuals, organizations and governments that want to undermine the legitimate processes.  I fully support using any and all means to ensure that only eligible individuals vote.  I'm also NOT in favor of advanced voting for convenience - it casts doubt as to whether people are voting multiple times or are ineligible.  PRESERVE THE INTEGRITY.  If you can't prove you're eligible, you can't vote.
