Philippine President Rodrigo Duterte revealed this week his intention to run for Vice President in the May elections. Critics say it’s a clear attempt by Mr. Duterte, 76, to shield himself from being prosecuted by the International Criminal Court for his “political crimes.”

Last year, the International Criminal Court (I.C.C.) decided there was enough evidence to establish that crimes against humanity were committed in Mr. Duterte’s deadly drug campaign, which has killed thousands.

Duterte has dominated his country’s politics since taking office five years ago, with an anti-drug campaign accused of hundreds of extrajudicial murders and a campaign of intimidation against opposition leaders and the media.

Duterte’s statement looked to be an attempt to maintain his political dynasty, according to former congresswoman Neri Colmenares, a human rights lawyer. He said that the president was taking advantage of the Constitution.

“He’s hoping to escape prosecution after he is out of power. It is not only legally insane but also exposes his real fear of going to prison,” Colmenares said.

With only a few months remaining in his six-year tenure, his critics worry he is laying the basis for a long stay in power.

He’s long toyed with the idea of continuing in government, even though he’s frequently stated in the last year that he’s tired of the presidency, which he claims has taken a toll on his health.

“All right, I will run for the vice presidency. Then I will continue the crusade,” Duterte said during a televised cabinet meeting.

Duterte’s choice puts him in direct conflict with his daughter, Sara Duterte, the mayor of Davao. She has grown in popularity as a possible successor to his father, despite the fact that she is not a member of his political party.
