For this sensible editorial on same-day registration.

Voter registration all the way up to Election Day is an idea full of hazard and cost, and yet a bill that would accomplish this sailed through the state Senate.  It is a bad idea, and the House should kill it.

The bill does not — assuming the Times is describing it correctly — have the most pernicious feature of Wisconsin's same-day registration, where votes are cast and counted — and then, several weeks later, the registrations are verified.  (I wish I were making that up, but I'm not.)  Wisconsin once had relatively clean elections; in recent years there have been significant problems with vote fraud there, and same-day registration contrbuted to those problems.

(Voters just to my north will be interested in the name of the principal sponsor of this bill: Eric Oemig.  He's compiling a record that should attract a quality Republican opponent in the next election.)
