President Obama has an Election Day ritual that he started in 2008 when he first ran:

He heads to the gym and plays basketball.

Wearing a Chicago White Sox baseball cap and carrying a pair of sneakers, Obama arrived about 8 a.m. Tuesday at Fort Lesley J. McNair in Washington, where he played basketball with friends, according to the White House pool report.

Obama did the same four years ago, on Nov. 6, 2012, when he played with Chicago Bulls Hall of Famer Scottie Pippen.

On Tuesday afternoon, Obama took to Facebook to talk about his ritual.

“I started an Election Day tradition on the court back in 2008. Not about to break it today. If you’ve got your own Election Day rituals, make sure one of them is casting your vote. It’s the most important American tradition we’ve got. So go vote — let’s finish what we started 8 years ago,” Obama wrote.
