Incumbent Lord Allan Jay Velasco, the son of Presbitero Velasco, Jr., an Associate Justice of the Supreme Court of the Philippines, is going up against Regina Ongsiako Reyes, daughter of provincial governor Carmencita Reyes and sister of Toll Regulatory Board Executive Director Edmundo Reyes, Jr. Velasco won against Edmundo Reyes in 2010; however, Reyes filed an election protest but the House of Representatives Electoral Tribunal dismissed Reyes' suit and even increase Velasco's lead an additional 39 votes after recounts.

Reyes was disqualified by the Commission on Elections' First Division after it ruled that she is a naturalized American citizen, which also caused her residency to be forfeited as the commission said that "she has not abandoned her domicile of choice in the USA." Reyes is allowed to appeal the decision to the commission en banc.^[1]
