The political opposition is likely to collapse in waves: public opinion seems to be moving towards intolerance, and any additional terrorist attacks related to Islam would continue the shift; the GOP controlled Congress may support Trump as vehemently as they have opposed Obama; the 105 federal judicial vacancies that should have been filled by Obama will instead be filled by Trump, possibly including multiple Supreme Court seats; and it will be very difficult for the companies themselves to fail to comply with court orders. For example, look at the huge battle to coerce Apple to unlock a single phone. Under a Trump presidency there would be substantially more pressure on tech companies.
My experience with conservative, religiously-motivated Americans (including many dear friend and family members) while growing up in a red state makes me think that (some subset) may be willing to tolerate substantial harm to themselves, the economy, and the founding principals of the USA so long as the "greater good" is achieved: prohibiting abortion, increasing the influence of Christianity on government, increased need for religious charity due to reduced social welfare programs, and the lower taxes that they've been told are a panacea. This makes me believe that compromising with Trump will look more like acquiescing to him.
I also think that some portion of the the conservative-leaning public was misled about Obama and were afraid of what they thought he would do, not what he said he would do. What could have been reasonable compromises about restricting certain types of gun sales and ownership, controlling healthcare costs through single payer policies or some other government intervention (which are considered mainstream in other first world countries) were opposed as a slippery slope to elimination of private gun ownership and destruction of American capitalism. These were not rational fears, but were effective at catalyzing conservative voters.
