Final answer:
Restricting voting to citizens aged 18 and over does not fail the strict scrutiny test for equal protection under the law. Age is a reasonable and objective criterion to determine eligibility for voting, as it correlates with the necessary maturity, knowledge, and responsibility to make informed decisions that affect the country's governance.
Step-by-step explanation:
Restricting voting to citizens aged 18 and over does not fail the strict scrutiny test for equal protection under the law. The strict scrutiny test requires that a law must serve a compelling government interest and be narrowly tailored to achieve that interest. The restriction is justified by the government's interest in ensuring that voters have the necessary maturity, knowledge, and responsibility to make informed decisions that affect the country's governance. Age is a reasonable and objective criterion to determine eligibility for voting, as it correlates with the attainment of these qualities.
