Some 600,000 citizens residing in the District of Columbia do not have the right to vote in the Congressional elections and some 4 million residents of US overseas territories do not have the right to vote in any federal elections. An estimated 5.8 million citizens are disenfranchised due to a criminal conviction, including some 2.6 million who have served their sentences.
Several Republican controlled state legislatures recently implemented laws requiring voters to show identification to vote, aiming to prevent potential impersonation. Democrats largely believe this could disenfranchise voters, particularly low-income and minority voters who may experience difficulties in acquiring the prescribed identification. (...) In 32 states voters will be required to show identification before voting, of which 16 require photo identification. The remaining 18 states and the District of Columbia establish the identity of voters, for example, through asking for personal information or comparing signatures to those on record.
