A Trump victory in Puerto Rican territory is unlikely, but a candidate could take control of the island, which is the largest U.S. territory without a governor or a president.
A Republican-controlled Congress and a Democratic-controlled Senate would make it more likely.
Puerto Rico, the United States territory most affected by Hurricane Maria, is the poorest state in the U.C.N. Caribbean region.
“We have an economic crisis and we have an international crisis,” said Juan Pablo Sanchez, Puerto Rico’s governor, in an interview with NBC News.
“It’s a real possibility.”
Puerto Rico is a U.N.-designated disaster area, meaning the U:1.5 billion island is already hit by a Category 3 hurricane, which could have catastrophic consequences.
The U.K.-based National Hurricane Center issued a hurricane warning for the island in early September.
President Donald Trump, who has vowed to rebuild Puerto Rico after Maria, has not yet made a decision on whether he will participate in the rebuilding effort.
His administration has said the island is in dire need of aid and it is considering whether to send aid to Puerto Rico.
