To be fair, Hillary is still a strong opponent and the Clinton family is a political powerhouse as far as Democrats go. I think Trump just had the right people on his team and he hit the campaign trail much harder than she did. At to why people like him, I think a lot of people just think he's entertaining lol. However, staunch Republicans love his hardline policies and stances.
I've been reading excerpts from this book. Despite all the noise thrown up by the Left and most of the media, the two authors got a glimpse into something similar to what I was seeing in the run-up to the 2016 election:
One of the reviewers ("Charles") at Amazon had an interesting point: "In particular, in all these groups the same three specific issues keep cropping up (along with some other issues that are more or less important to specific groups). Given the significant differences across these sets of people, this consistency is surprising. These three issues are who controls the Supreme Court, gun rights, and, most interestingly, the habit Obama had of apologizing, purportedly on behalf of the United States. (As all such studies find, and utterly contrary to the view of progressives, racial issues almost never crop up, and illegal immigrants less than you would expect.) The first two have a straightforward analysis—Democrats have for decades tried to evade democratic rule by using the Supreme Court as a leftist super-legislature, and Republican voters are well aware of that. Gun rights require even less discussion—in fact, in the past few months, driven mad by anti-Trump frenzy, prominent Democrats have begun openly declaring what they always lied about in the past, but which has always been true—that yes, they want to take away every single gun normal Americans own."
