Duterte wins Philippines presidential election, should foreigners worry?

Duterte becomes Philippines president should foreigners worry? In all honesty I don’t think so. The only risk of something going wrong is if someone tries to fix the election. There has been claims of machine tampering from Hong Kong for example so already there is flames on the fire relating to corruption and vote fixing.
But if Duterte does take power he hasn’t made any negative claims relating to foreigners in the Philippines or in relation to future arrivals. If anything I can see problems for those that are corrupt and criminal in the Philippines. Where the average expat is quietly minding their own business living out their life in the tropical Philippines.
