Yes.
Anyone interested in a review of the current rules for early voting in all the states can see a breakdown here: http://www.longdistancevoter.org/early_voting_rules
As I previously mentioned, some states don't allow it at all. Others may limit it to 10 days before the election and still others may exclude weekends from their early voting time frame.
It certainly makes me wonder why Ohio was singled out for prosecution by the Justice Department.
