"](CNN) - An issue unique to Puerto Rico appears to be dividing supporters of Hillary Clinton and Barack Obama: whether the current U.S. territory should become a state or not.
Neither candidate has taken a direct position on the issue, though Puerto Rico's former governor, who has advocated statehood, supports Clinton.
According to CNN's exclusive exit polls, Clinton supporters there heavily back statehood for the commonwealth, while Obama's do not. Among Clinton supporters, 72 percent want it to be a U.S. state, 23 percent want it to remain a commonwealth, and 2 percent want it to be an independent country.
But among Obama supporters, 57 percent want Puerto Rico to stay a commonwealth while only 34 percent want it to be a U.S. state. Eight percent want it to be an independent country.
