The day after history was made, the reality of a Donald Trump presidency is beginning to sink in in the United States.
The billionaire businessman's unexpected victory paid off for the Republican party itself, which controls the presidency and both chambers of Congress for the first time in nine years.
First up in the firing line is Obamacare, the medical legislation Republican Senate leader Mitch McConnell maintains is the worst legislation passed in Barack Obama's presidency.
"It's a pretty hot item on our agenda, as you know, and I would be shocked if we didn't move forward to keep our commitment to the American people. It was the single worst piece of legislation among many bad pieces of legislation passed in the first two years of the Obama presidency. The sooner we can go in a different direction, the better."
Dr Rodrigo Praino, a politics and public-policy lecturer at South Australia's Flinders University, points out proposals can still be blocked by a filibuster, though.
He says, while getting rid of Obamacare will be relatively straightforward, many other plans of Mr Trump's will be more difficult to turn into reality.
"His relationship with the Republican leadership has been difficult from the beginning. Him being an outsider that essentially hijacked the nomination of the Republican party will not help. So what happens is that Donald Trump, every single policy proposal that he has, he will have to coordinate with every individual member of the Republican party in order to obtain their individual support. There is no such thing as a party line that the members are required to follow, like we would have in Australia. So he's not going to have a very easy time dealing with even the Republican Congress."
Dr Praino says many of Mr Trump's signature campaign promises could also face difficulties.
"Donald Trump is going to try to put forward at least the most notable of his promises. So, for example, the wall in Mexico is somehow going to move forward. But now, what I think we have to keep in mind is the fact that the wall itself can happen in many forms. He could theoretically find a way to fulfil the campaign promise without actually building a brick-and-cement wall that we have been imagining for all these months. So I think that there will be ways that he will try to implement his policies in ways that are feasible and that may not look exactly like we think they will look today, especially because he will need to gain the approval of a Republican majority in Congress that is kind of hostile to him."
Throughout his campaign, President-elect Trump clashed with several high-profile Republicans, including Speaker of the House Paul Ryan, who he described as "weak."
Speaking after the election result, though, Mr Ryan has simply praised Mr Trump for uniting the government.
"So with unified, Republican government, we can fix this, we can fix these problems. Look, it's not just the healthcare law that we can replace, because we now have shown the willingness and the ability to do it. There's so many more things I'm excited about. Think about the laid-off coal workers now who see relief coming. Think about the farmers here in Wisconsin who are being harassed by the EPA* and the waters of the USA. Think about the ranchers in the West who are getting harassed by the Interior Department, or the laid-off timber workers. There is relief coming."
Other legislation under threat includes tighter greenhouse-emissions regulations for power plants and relaxed travel restrictions for Cuba.
Mr Trump has also promised to overturn many pieces of legislation pushed through via executive order by Mr Obama.
That includes his proposal to protect millions of illegal immigrants from deportation.
The return of a Republican to the White House also resolves the issue of appointing a new Supreme Court justice to replace the late Antonin Scalia, considered a conservative judge.
The Republican-led Congress had refused to endorse President Obama's choice of the less conservative Merrick Garland, saying they would wait until after the election.
Dr Praino, at Flinders University, says the likelihood of more vacancies occurring during Mr Trump's term means the bench could become dominated by what are deemed conservatives.
He says that could have a major long-term impact.
"The problem is that many of the remaining justices in the Supreme Court are ageing. They are going to be retiring or they are going to pass away at a certain point, which means that there will be other vacancies in the court. And, at that point, things will change. We should expect very harsh decisions in terms of abortion. We should expect decisions against gun control. We should expect decisions even maybe against gay marriage. We should remember the fact that the Supreme Court will outlive the Trump presidency, because Supreme Court justices are nominated and confirmed for life. So when Donald Trump finishes his four years, if he has the possibility and the ability to nominate more than one justice and change that balance of power of the court, that new conservative court could be in charge for 10, 15, 20 years."
Mr Trump takes over as president on January the 20th.
