The voting device reads and counts the ballot when it is inserted in the voting device. The voting device detects some common mistakes voters make when marking their ballots. The voting device also prints a message that explains why the ballot was returned. The voter then can get a new ballot to mark again correctly so that all his or her votes count. Exit Polls People who conduct exit polls sometimes approach voters as they leave the polling place.
Exit polls are unofficial surveys of voters usually conducted by news media.
Election officials do not conduct exit polls. People who conduct exit polls within 300 feet of the ballot box must display identification. Participation in exit polls is voluntary.
