At first, a minor issue erupted as to who would be the official candidate of Lakas-Kampi-CMD in the district: Roman or the governor's daughter, Maria Angela "Gila" Garcia.

In an en banc decision however, the Comelec later ruled that Roman is the official Lakas-Kampi-CMD candidate, making Garcia the independent one.

He will face 2007 challenger and former three-term Guiguinto, Bulacan mayor Ambrosio "Boy" Cruz Jr.

The Josons are the ones being shortlisted by local party Bagong Lakas ng Nueva Ecija (BALANE) for the provincial governorship, with first district representative Eduardo Nonato N. Joson, Eduardo's nephew vice governor Edward Thomas and Tomas III.

Umali's governance was seen as "worse than the Josons" and several local officials identified with Lakas Kampi CMD said they are willing to cross party lines to support the Eduardo.

Umali created the local party Unang Sigaw, Partido ng Pagbabago as an answer to the Joson's BALANE.

Incumbent Eduardo Nonato N. Joson (independent) won't run to concentrate on bringing the Bagong Lakas ng Nueva Ecija party to power in the province.

As early as late June 2009, several residents in the district had expressed optimism of having the president as their representative in Congress.

Representative Arroyo, on the other hand, has apparently given way to his mother's own congressional bid, Pineda said; meanwhile, professor David has backed out of the race.

[16] On November 30, 2009, after much speculation, President Arroyo announced on the Philippine Broadcasting Service her congressional bid for the second district of Pampanga.

[17] The president filed her certificate of candidacy on December 1, and her son Mikey retired from politics to give way for her mother to run.

Meanwhile, Feliciano Serrano, an electronics engineer graduate of the University of Santo Tomas from Porac, also filed his own certificate of candidacy as an independent.

[18] The Liberal Party did find a candidate in Adonis Simpao, a civic society leader from Guagua.

Simpao, a graduate of Don Honorio Ventura College of Arts and Trade in Bacolor, had no plans of running, but then governor Eddie Panlilio persuaded him on the eve of the last day of filing of certificates of candidacies.

[19] Representative Risa Hontiveros-Baraquel of the AKBAYAN party-list, who is running as one of the senatorial candidates of the Liberal Party, revealed that the president poured in 459 million pesos on infrastructure projects solely for the district.

[22] Lakas Kampi CMD leaders had said that they will field the president as Speaker of the Philippine House of Representatives; the ruling party has more than 100 incumbents running in the House elections, and several running unopposed or by token opposition, Lakas-Kampi predicts an overwhelming number of their candidates will win their respective races, and that the president will have an easy time of being elected as speaker.

She will face perennial challenger and former Undersecretary Rene Maglanque, who enjoys the support of both the Liberal Party and the Nationalist People's Coalition.

Incumbent Monica Prieto-Teodoro (Lakas-Kampi-CMD), wife of presidential candidate Gilberto Teodoro decided to quit politics to support her husband's bid for presidency.

Incumbent Jose Villa Agustin Yap (Lakas Kampi CMD), who was supposed to run again for re-election, died on March 2, 2010.
