Guam's next delegate to Congress will be decided in a runoff election after none of the three candidates secured the minimum 51 percent of votes needed to win outright.
The Guam Daily Post reported the incumbent San Nicolas polling the highest of the three with 13,000 votes which is 45.9 percent of the 28,293 votes cast.
Fellow democrat and former delegate Robert Underwood polled 9,300 that is 32.87 percent of votes.
And republican William Castro received 5,942 or 21 percent of votes.
San Nicolas reportedly asked his fellow Democrat contender to consider a 'gentleman's withdrawal'.
Robert Underwood rejected the appeal saying to do so would be to ignore the 54 percent of people who signalled a desire for a change in leadership by not voting for Nicolas.
