- @POTUS twitter account is going to start tweeting at 3AM
- I think illegal immigration enforcement could see the most drastic and immediate change. To my knowledge the status quo is not legislated in any way, and was created by preventing enforcement rather than any legal means. When low-skill unemployment bottoms out the motivation will start to weaken.
- whatever was done by Obama by executive order, I presume will be quickly undone, they will probably have reams of documents ready to be signed on day 1.
- Hillary Clinton: in order to prosecute Trump will need to nominate a new Attorney General to the DOJ, and then ask the FBI to re-assess I guess? I don't think she will go to jail, in some countries when power changes the losers get jailed but it hasn't been the case in America, and I don't think high level politicians want it to become the case. For all practical purposes I think Clinton will continue to be above the law.
- The WALL ... boy I don't know. I will be fascinating to watch if he tries to do this. The only utility will be economic stimulus.
- Trade war: I think the American dollar will go to a lower level which will decrease imports and increase exports.
- Muslim ban: I think he will disallow visas from active conflict areas and nearby. I don't think i.e. Malaysia will be effected, or Indian muslims for example. Maybe countries that aren't functional enough to carry out a criminal background check will be disallowed.
EDIT:
Also, I don't think Trump+GOP will enact or seek to promote any racist or sexist policies, I don't think they will mount an attack on the recent marriage equality ruling. I think the following people will suffer financially:
- undocumented immigrants
- industries that depend on a close relationship with the government: the guard is changing -- if you had relationships with the Bushes and the Clintons, you've had access to the most powerful organization to ever exist in the world for the past 27 years, that may or may not continue.
This is if Trump lives all four years. All of the above doesn't apply to Pence, I think Pence could do some real damage.
