Both Washington and Oregon allow ballots to be postmarked on election day and still count.....that means a delay in reporting, since they have to wait for all the ballots to come in.
Most other early voting states require the ballots to be delivered by the close of polling, in Colorado, early in-person voting (a popular option) closed Friday, so the ballots can be sorted and delivered to the proper precincts by Tuesday.
In the case of Oregon, that's completely wrong. The ballot must be in the hands of the elections dept. by 7 PM on election day. Postmarks don't count. They always remind voters who wait until a few days before election day to NOT mail in the ballot, instead to drop it off in person.
