Bernie Sanders won at least one precinct in Nevada today by chance.

Video shows reps for Joe Biden and Sanders drawing a card to see who would win the unknown location.

Watch:

Each person drew a card, and flipped them over simultaneously.

Sanders drew a higher card, and thus won.

This was standard procedure for the Nevada caucuses.

“In Iowa, they flipped a coin,” CNN’s Dana Bash reported, adding that Nevada was doing it “Vegas-style” with cards.

“If there’s a tie, the tie goes to the high card,” MSNBC reported about the rule.
