I voted absentee, by mail, in WA. (All ballots in WA are vote by mail, mine just happens to get mailed to TX.)
I will note that the Mrs. and I received our ballots in plenty of time to send them back. Also that the Thurston County Auditor (in WA, responsible for ballots at the country level) has ALWAYS gotten me my ballot on time - even when I was in Afghanistan, and had moved to a different FOB than the one whose address I had given her office. She is currently running for WA Secretary of State, and got my vote based on her the outstanding performance of her previous job.
