A lesson in democracy

The students of Marjory Stoneman Douglas High School have inspired a nationwide school walkout Wednesday to protest insane gun laws. Good. At 10 a.m., for 17 minutes for the 17 victims, youngsters across America will put aside their lessons and stand together in powerful purpose.

Walking out or not, high school seniors and juniors should use these moments to go beyond making a statement. They should register to vote.

Just 50% of Americans aged 18-29 (less among New Yorkers) cast ballots in 2016. For shame.

In New York, any 18-year-old who is a U.S. citizen can sign up, as can 17-year-olds who will be 18 by Dec. 31. They will become active voters on their 18th birthday and can then cast their ballots.

To make it easy, we have printed a voter registration form on the back of the opposite page. Tear it out, copy it for your friends and fill it out. You can also download forms at vote.nyc.

Walk out today if the spirit moves you. More important, show up that Tuesday in November.
