In the U.S., some 4.6 million people are disenfranchised due to a felony conviction

An estimated 2% of the voting age population in the United States will be ineligible to cast ballots during this year's midterm elections due to state laws banning people with felony convictions from voting.

That's according to research released Tuesday by the Sentencing Project, a nonprofit organization that advocates for restoration of voting rights for people with prior felony convictions.
