eighteen year olds aren't old enough to vote

The 26Th amendment (Voting age nationally established at eighteen) lowered the voting age from twenty-one to eighteen on July1,1971, but was it a smart move? Many people argued that if a person can go to war than they should also be able to vote. Although I understand what the people are saying, I feel that eighteen year old are not mature enough to vote. I feel this way because i see many of them joke about voting. They don't value the virtue of it. They take advantage of their new found privilege and mistreat it by either not voting or voting for a candidate whose motives are villainy. Voting during elections is a very serious thing because the outcome of the elections would affect the American people. Voting for a strong and qualified candidate, signifies the United States as a strong nation. The saying "Age comes with wisdom" would represent this; the older a person gets the wiser they become. Therefore eighteen year old shouldn't have the privilege to vote. They should wait until they are older like when they are twenty-one.
