This lawsuit just filed in Florida. Apparently, under Florida law (or current interpretation), if you fail to sign an absentee ballot, a postcard (? not clear in the Politico story) citizens have a chance to “cure” the error by coming in, providing proof of identity, and signing an affidavit.
But if your signature doesn’t match, either because it has changed (the focus of the lawsuit) but also presumably if the outside envelope has water damage, your pen leaks, any of a variety of problems, you have no similar chance.
What a strange law. I don’t know the details in every state, but certainly in Oregon and Washington, if there is a problem with your signature (or your vote by mail ballot comes back undeliverable), a postcard is immediately generated and sent to you, and you have until 14 days after Election Day (in Oregon) to correct the error.
Florida already has a system in place to “cure” one set of ballots. What possible policy rationale is there for denying this to the relatively small number of ballots where signatures don’t match?
