It’s also just a general bad idea. Turnout is a measure of the validity of an election result and support for the democratic process. That’s lost (no, blank and absentee does not send the same message).

What you want is to make it easy to vote, and encourage it. Remove registration requirements. Make sure it never takes more than 15 minutes. Make sure it’s easy to know/find/access the polling place. Make elections be on holidays or sundays.
