Mashpee Middle-High School students participated in a mock election Wednesday, and if it were up to them, Donald Trump would be the next president of the United States.

Republican Trump received 33.6 percent of the 634 votes cast, narrowly defeating Democrat Hillary Clinton, who received 32.5 percent of the vote. Independent Gary Johnson received 21.9 percent of the vote, while the Green Party’s Jill Stein was favored by 12 percent of the young voters.

Students in grades 9-12 also voted on the state’s four ballot questions. They approved legalizing marijuana by a 57.3 to 42.7 percent margin, said yes to expanding charter schools by a 51.9 to 48.1 percent vote, and easily passed referendum initiatives proposing expanded slot-machine gaming and improved conditions for farm animals.

“A mock election is a critical tool that makes them (the students) critically think,” said Deb Vaughn, an English and AP Language and Composition teacher at the school, who coordinated the event. ”I’m all about promoting civic responsibility and getting the students to understand the importance of voting.”
