Mail-in ballots are voting tools that allow individuals to cast their votes by mail rather than in person at polling places. Voters receive a ballot in the mail, which they fill out and return by a specified deadline. This method is often used to increase accessibility for those who may have difficulty voting in person, such as the elderly or those living far from polling locations. To ensure the integrity of the election process, mail-in ballots typically require voters to provide identification or a signature that matches their registration. Many states, including California and Florida, have implemented mail-in voting to accommodate various needs and preferences, making it easier for citizens to participate in the democratic process.
