Gov. Scott Walker said he thinks that it would "much better" if Wisconsin did not have same-day voter registration.
Walker made the comments during a speech Friday night in California.
Walker's spokesman Cullen Werwie had nothing to add Monday to what Walker said.
Walker said in the speech that "It would be much better if registration was done in advance of Election Day, easier for our clerks to handle that."
Incoming Republican Assembly Speaker Robin Vos has supported doing away with same-day voter registration in the past and sponsored a bill to do that when Democrat Jim Doyle was governor.
Vos said Monday he was open to the idea, but he did not know of anyone who planned to propose it and he had not spoken with Walker about it.
