Was Trump's Republican nomination a "protest vote" by Republicans?
Or, did enough of them honestly feel he was the best candidate?
The difference between the Democrats and the Republicans is the Democrats are not afraid to lie and cheat. They belief in relative morality and the ends justified the means. Hillary rigged the election against Bernie and even took over the DNC finances, before she was nominated. The Republican establishment, by its connections to the Constitution and Religion, plays more by the rules of old fashion right and wrong and ended up with Trump nominated, to everyone's surprise. If the Democrats had not cheated, Trump may have faced Bernie. This would have been the Democrat surprise.
The Republican leadership never expected Trump to win the nomination. However, since Trump was a billionaire and a TV celebrity, all the candidates thought he would fail, but still be a healthy donor and cheer leader for the Republican nominee. The images of large future donations from Trump froze the other candidates in the early going, This allowed Trump's momentum to build. The prospect of donations by Trump is why the candidates did not insult Trump, so vigorously. It was very controlled. They needed to walk the line. This played to Trump's advantage. The main weakness of all politicians is they need to kiss up for money. Trump self financed to avoid the kiss up. He could go after anyone and not fear parallel donors.
The leftist media also helped Trump, during the Republican primary. This helped their own failing audience numbers. It turned out that anything Trump sold media time. Trump pulled CNN and the NY times from the dump. However, the real goal of the main street media was undermining the Republican party using Trump as the hammer. They wanted Trump to damage the other mainline candidates and then the Republican nominee lose to the Hillary machine. This plan would backfire on them. Thank CNN and the NY times for Trump's rise and early momentum that made him unstoppable. Trump called them fake news. The goal was to make the swamp come out of the shadows and be seen via their all out attack.
The reason Trump did well in the general election is he took on the Obama and Clinton swamp. This helped to unify the Republicans and draw in Independents. Everyone saw the corruption under Obama and Hillary and how this was swept under the rug. The IRS scandal, for example, was seen as corruption in government, even though Obama was all to sweep it under the rug. Hillary erasing e-mails was not good. Nobody was fooled. People wanted change and Trump showed that he was capable of taking on corrupt the status quo.
Trump has survived one year of an all out propaganda assault and media hazing. He has gained in popularity. This future was seen by his supporters, early. Trump's stamina has also caused Republicans, who once hated Trump, to be part of his team. Trump is unorthodox but effective. He is not the TV ready President, the left likes. He is someone who gets things done while creating PC cringe. This is funny to watch, if you have a sense of humor.
