Final answer:
The claim that Motor-voter registrants are more likely to vote is false; while the Motor Voter act increased registrations, it did not significantly boost voter turnout.
Step-by-step explanation:
The statement that Motor-voter registrants are more likely to vote than other new registrants is false. The National Voter Registration Act, also known as the Motor Voter act, was designed to simplify the voter registration process by allowing citizens to register to vote when applying for or renewing their driver's licenses, as well as when signing up for Social Security benefits. Although this increased registrations substantially, evidence suggests that it did not significantly increase voter turnout.
In fact, voter turnout slightly decreased in the two years following the act's passage. People who used the expedited system were mostly those who were already intending to vote. Different factors, such as age, frequency of relocation, and levels of engagement in government and politics, can influence an individual's likelihood to vote more than merely facilitating the registration process.
