The deadline for ballots is today

But I don't know when the results are to be reported.

According to CNN, it's scheduled for March 22

FiveThirtyEight has Dems abroad listed on May 14 in it's table on delegate tracker page.

As far as Mississippi and Michigan, doesn't look like final allocations are up.

Of the 36 Mississippi delegates, AP shows 29 allocated to Hillary, and 4 to Bernie. But that doesn't added up to 36, so I guess we have to wait and see what they do with the remaining 3.

Of the 130 Michigan delegates, AP reports 65 allocated to Bernie, and 58 allocated to Hillary. Once again, doesn't add up to 130, so I guess we have to wait what they do with the remaining 7.

What a day, huh?

Thanks so much for the info!

This page states that the official count will be done on March 21st and results announced when that's finished. Unsure where this happens geographically (re time zone), so it could be 3/21 or 3/22 at that point.
