Do you think 18-year-olds should be allowed to vote?

I have seen several questions regarding 18-year-olds being too immature to be in romantic relationships with older people (e. g., 18 with 24). If that age is too immature to decide to date someone older, are they mature enough to decide who our leaders are?

Eighteen is old enough to vote.
Eighteen is not old enough to vote.
