If three is a crowd, 15 is far too many.

CNN reported on March 21 that 15 Democrats have announced their 2020 presidential candidacy so far, including exploratory committees. And while it’s certainly favorable to have many options from which to choose, this plethora of candidates could ruin the party’s chances of regaining the presidency in 2020.

Sens. Cory Booker, Kirsten Gillibrand, Kamala Harris, Amy Klobuchar, Bernie Sanders and Elizabeth Warren have announced that they will run for president. Former Secretary of Housing and Urban Development Julián Castro, former Maryland Rep. John Delaney, Rep. Tulsi Gabbard, former Gov. John Hickenlooper, Gov. Jay Inslee, former Rep. Beto O’Rourke, author Marianne Williamson, businessman Andrew Yang, South Bend Mayor Pete Buttigieg and Miramar Mayor Wayne Messam have also expressed interest in presidential candidacy.

If that verbose list doesn’t make your head spin, I don’t know what will. It certainly leaves me perplexed.

American Democrats are left with piles of research to accomplish before the election if they wish to make an informed decision on Nov. 3, 2020.

Statistics say that they simply won’t. The choice seems daunting, so many Americans just don’t vote. According to PBS, a mere 58 percent of those eligible voted during the 2016 presidential election.

Historically, when a party has multiple candidates, the voters of that party are split and decrease its chances to gain the presidency. Take, for example, the election of 2016: Democratic voters chose between Hillary Clinton and Sanders, while Republicans were mostly united behind Donald Trump. As a result, Trump won.

As George Washington said, “We should not look back unless it is to derive useful lessons from past errors, and for the purpose of profiting by dearly bought experience.”

It’s time for at least half of the Democratic candidates to rescind their candidacies. Let’s not repeat history.
