When you approach the check-in table, first tell the poll worker the name of street where you live, then the number of your residence and finally your name. As the voters list is arranged by street, this is the quickest way to receive your ballot and keep any lines moving.
In a primary election, voters who are registered in a political party may only obtain a ballot for that party. All other voters may request the ballot of any party participating in the primary election. You will not become registered in a political party because of your participation in a state primary.
