After losing the Democratic presidential nomination to Hillary Clinton in 2016, Sen. Bernie Sanders, I-Vt., announced on Feb. 19 that he will be running for president again in 2020.

Bernie Sanders, or commonly referred to as Bernie, has gained an immense amount of supporters already, raising more than $1 million for his campaign in less than four hours after his announcement, according to CBS News.

A democratic socialist, Sanders advocates for raising the national minimum wage to $15 an hour, a single-payer healthcare system, free college and the legalization of recreational marijuana. He has gained many supporters, particularly among young voters, by advocating for these policies.

However, one main aspect that seems to be making some people weary of supporting him is his age. The senator is currently 77 years old.

Some people have commented that if Sanders were elected he wouldn’t make it to his full term due to his age but, honestly, age shouldn’t matter when deciding whether or not a candidate is qualified for the position of president.

Our current president Donald Trump is 72 years old, only five years younger than Bernie, and no one really expresses concern about his age, even though Trump seems to have more health concerns than Sanders.

When it comes down to it, Bernie Sanders is qualified to be president and has proven this with decades of service in the United States House of Representatives and Senate. To denigrate these qualifications because of his age is not a sound argument. In fact, it is a prime example of ageism.

When voting for a presidential candidate, voters should look for someone who shares their values and have beliefs that line up with their own, instead of focusing on age.
