A question about voting and changing my address

[BlondeSpiders]

I'm reading this awful Atlantic article What if Trump Refuses to Concede? and it started me thinking.

I expect to get my ballot in mid-October. My goal is to complete and put it in a dropbox immediately. I plan to move from my Seattle home to an Edmonds home at the end of October, and I'll need to surrender all my keys (mailbox key too) to the landlord by 10/30 or 31. I was planning to change my address with the post office on 10/30.

Could changing my address before the election in any way invalidate my ballot? If I send it mid October, it should be counted fairly quickly, yes?

Reading all the ways 45 plans to contest mail-in ballots has me shook. What do you think?

I don't think moving will invalidate your vote. You'll be moving from King to Snohomish county, so you won't be able to vote on any Snoho matters this time - but that won't invalidate your Nov. Ballot, just one of those weird in-between transition things imo.

Eta - yes, just send in your ballot asap, everyone should do so! You can track your ballot if you're worried

Put in your mailing change of address but don't change your voter registration until after the election. You can maintain your old address for voting purposes until you update your voter registration. Waiting to update your voter registration should make the argument invalid, and your vote valid.

From the SoS website:

You may only be registered to vote at one location, even if you own multiple residences. If you move or are temporarily away, you may maintain your voter registration at that address until you register to vote elsewhere.
