Yes. I'm assuming it is the book managed by the poll worker; that those listed as voting asked for a Democrat primary ballot on 6/3. I don't know that for a certainty. It would be good if someone in MS can confirm this.
And that if you walked in and asked for a GOP ballot on 6/3 you would be listed, not in the Democrat Poll Book, but in the Republican Poll Book.. They probably both have a column for 6/24 as a contingency as someone explained upthread.
Still, it would be good to have MS confirmation of this.
