The non-voting delegate is elected for a two-year term. Incumbent freshman Delegate Rep. Michael San Nicolas, who was first elected in 2018, is seeking a second term. He was challenged by former U.S. Rep. Robert A. Underwood (Guam delegate from 1993 to 2003), a Democrat, and Republican Wil Castro. As no one got a majority of the vote, San Nicolas and Underwood faced off in a runoff within two weeks. The Guam Election Commission set the runoff election for Tuesday, November 17, 2020.[1]
