"Saturday will be 7am to 7 pm, Sunday from 1-to-6 pm and 7am to 7pm all next week."
Any registered voter can vote in any party's primary you will make that declaration when you show up to vote. That will be different if there's a need for a run-off.
"In the April run-off, you'll need to vote in the same party's run-off, you can't switch parties and vote in a different party's run-off election in April."
