As primary elections take place around the country this spring, one state will be trying out a new way of deciding who wins. Maine is set to become the first state in the country to use a method called "ranked-choice voting," in which voters rank each candidate on the ballot rather than picking just one. The system is designed to eliminate candidates one by one until a winner emerges with more than 50 percent of the vote. Advocates say it will make elections more democratic. But as NewsHour Weekend's Hari Sreenivasan reports, not everyone in Maine understands or supports the new system.
