Shooting criminals tends to lower the desire to commit criminal acts. I have always said that if the state put every third car thieve to death, car theft would not exist.
The Philippians, like Americans, are becoming sick of self serving politicians who promise change but never deliver. If the policy lowers crime, especially violent crime, dramatically. I suspect the new President will enjoy a resounding land slide reelection.
The president is only allowed one six-year term, unless he fills in for a predecessor who does not complete the term. We saw that when Joseph Estrada was elected in 1998 and impeached two years later. He was succeeded by Gloria Macapagal Arroyo, and because her first term lasted for four years, she was allowed to run once more, and thus was in office for a full decade, from 2000 to 2010.
