Voters selected candidates for all local positions: a town mayor, vice mayor and town councilors, as well as members of the Sangguniang Panlalawigan, a vice-governor, a governor and a representative for the lone district of Marinduque in the House of Representatives.

In addition, the ruling notes that Reyes did not submit sufficient evidence that she had been resident in Marinduque for at least one year, citing documents which point to her term as Provincial Administrator.

[2] But Commission on Election Chairman Sixto Brillantes in his dissenting opinion pointed that the evidence presented by Velasco's camp is a double hearsay and inadmissible since it was never sworn nor authenticated by the issuing officer and it was taken in an internet blog of unknown blogger.

Thus, Representative Regina Ongsiako Reyes was the seating Congresswoman of the Lone District of Marinduque but did not finish her 3-year term as she was later removed from her post and replaced by Velasco in February 2016.

Incumbent governor Carmencita Reyes is running for a second term, having assumed the governorship after defeating then-incumbent Jose Antonio Carrion in the 2010 election, alongside her running mate, vice governor Antonio Uy Jr.

However, he does not have a running mate; instead, the NUP is endorsing Melecio Go of the Nacionalista Party for the position of vice governor.

His running mate is Jose Alvarez, who previously sat as a member of the Sangguniang Panlalawigan for the province's first district.

Despite being disqualified by the Comelec en banc, Regina Ongsiako Reyes was proclaimed anyway by the Provincial Board of Canvassers on May 15, 2013, although the camp of Lord Allan Jay Velasco attempted to stop the proclamation.

Incumbent vice-mayor Sebastian Mandalihan is term limited and running for provincial board membership.
