To me personally the worse thing about a Trump win is OC being right (that would be a bitter bitter pill) other than that I suppose SC nominations could be a little painful and clean energy initiatives might be set back
but I've come to terms with GW, where I live and with how long I'll probably live the most I'll have to endure is probably some uncomfortable summer heat and increased AC bills - the flooding, hurricanes, tornadoes, sea water infiltration, Zika and other plagues will probably hit the pray harder states- California will probably continue to experience drought but if anyone can afford to desalinate it's them.
Also I think Trump will do some good things like reduce income inequality ( I think he'll do it by knocking 45% off the stock market but hey)
Build the wall, tax cut, hire what 100,000- 400,000 government workers to deport 13 mil illegal aliens, increase military spending 40% - put that together and that's the mother of all Keynesian stimulus programs
Other than that who knows Trump's mouth is completely untethered from reality but one thing for sure is the Republicans own everything for good or ill.
