Twenty-second Amendment to the United States Constitution
The amendment prohibits any individual who has been elected president twice from being elected again. Under the amendment, an individual who fills an unexpired presidential term lasting greater than two years is also prohibited from winning election as president more than once. Scholars debate whether the amendment prohibits affected individuals from succeeding to the presidency under any circumstances or whether it only applies to presidential elections.
Felony disenfranchisement
Felony disenfranchisement was a topic of debate during the 2012 Republican presidential primary. Primary candidate Rick Santorum from Pennsylvania argued for the restoration of voting rights for convicted felons who had completed sentences and parole/probation. Santorum's position was attacked and distorted by Mitt Romney, who alleged that Santorum supported voting rights for felons while incarcerated. Former President Barack Obama supports voting rights for ex-offenders.
