Rodrigo Duterte (L) and Alan Peter Cayetano (R)

Metro Manila (CNN Philippines) — After months of speculation, it's now clear who's with who. And for the Partido Demokratiko Pilipino-Lakas ng Bayan (PDP-Laban), it's Duterte-Cayetano.

The party formally endorsed the presidential and vice presidential tandem on Monday (November 30) as its official bets for the highest posts of the land.

And Davao City Mayor Rodrigo "Rody" Duterte threw his full support behind his running mate.

In his speech, which lasted for more than an hour, Duterte told the audience, that if they won't vote for Sen. Alan Peter Cayetano, then they might as well don't bother voting for him.

The iron-fisted mayor pushed his platform of zero crime and zero corruption, saying that crime had to stop as the people had lost the privilege of walking the streets safely.

On the peace process, Duterte said the proposed Bangsamoro Basic Law (BBL) was designed to take care of the Moro people in Mindanao and that the region was "the salvation of the country."

He also said he would carry out inclusive peace talks with Nur Misuari, leader of the Moro National Liberation Front (MNLF), and exiled communist leader Jose Maria Sison.

The mayor said he was also intent on reorganizing the government by adopting a federal structure, saying it would be beneficial for all.

He also compared Davao to Metro Manila and said he would make sure the the government system would be swift.

On the South China Sea issue, he said Filipino fishermen must be left alone because it meant food security for the country. He disagreed with going to war with China and said he would rather talk to them instead.

Duterte took a swipe at Sen. Grace Poe's citizenship again, saying that he was running as a matter of principle and that his reason for running was not flimsy as it was a constitutional issue.

The no-nonsense mayor did not spare anyone, not even Pope Francis, when he railed against the heavy traffic during the papal visit.

Duterte still has to deal with legal obstacles concerning his certificate of candidacy (COC) to substitute for Martin Diño. A petition to nullify Duterte's COC has already been filed on the same day he announced his presidential run last Friday.

He commented on the disqualification bid but his answer was not exactly what his supporters wanted to hear.

"Kapag ma-disqualify ako, I'll go home and retire from public office."

[Translation: "Should I be disqualified, I'll go home and retire from public office."]

It can be recalled that last Monday (November 23), Duterte said he would fight up to the Supreme Court should anyone challenged his presidential bid.
