He is running under the Nacionalista Party against Liberal Party's re-electionist Vilma Santos-Recto. Too bad, I was planning to vote for him.
Sanchez was rushed to the hospital yesterday (April 26) when he complained of dizziness and collapsed during his campaign sortie. He was at the ICU since then. The cause of death was cardiopulmonary arrest and organ failure.
Condolences to those he left behind.
