The legitimacy source of political powers in democratic systems is fair and honest elections. Another issue that is just as important as the fair and honest conduct of the elections is the voter turnout rate of elections. Even if the elections are held fairly and honestly, if the voter turnout rate is low, this may pose a relative legitimacy problem. It can be said that there is a direct proportion between the voter turnout rate of elections and the legitimacy rate of the political power. Public authorities use some methods such as electronic voting and mail-in voting in order to increase their voter turnout rate in elections. In order to increase abroad voter turnout rate in our country, the Law on Basic Provisions of Elections and Voter Registers was amended in 2008, mail voting and electronic voting were added. Although mail-in voting and electronic voting methods increase voter turnout rates, they have the potential to cast doubt on the reliability of the election. In this study, in light of the discussions that started after the presidential election of the United States of America in November 2020, electronic voting and mail voting methods will be evaluated.
