Texas tried to purge its voter rolls by sending mail to potentially dead people. A judge temporarily blocked the effort after 4 voters filed a lawsuit. How do you suppose those letters went?
Dear Sir or Madam,
We think you might be dead. If you're not, please give us a holler and thank goodness we haven't lost a taxpayer. If we don't hear from you in 30 days, whether you receive this letter or not, and whether we receive your reply or not, or whether we decide to "lose" your reply, then you won't be able to vote anymore.
If you really are dead, so sorry for disturbing you. We will forward all tax inquiries to your surviving relatives. And you still won't be able to vote anymore.
Your friendly neighborhood government agency
Hey Texas, don't you have bigger problems like drought and stuff?
