your post is chock full of simply ridiculous claims and this one is the crowning piece. please supply *any* actual documentation for any of these made up ideas. Trump shot up in popularity because he ran in primaries, he had plenty of money to do so as well as a lot of backers (both domestic and foreign, we were to learn) all around the country and conservative voters liked his ideas (mostly the anti-immigrant rhetoric, which is the oldest song in the conservative catalog, as well as a deep well of hatred for HRC that had been developed by conservative interests for literally decades) the best, plain and simple. FOX news would have built him up ahead of time as they are a right wing propaganda outlet that most certainly did want to create a Trump candidacy, sure. however "Left wing media" or even "mainstream" media outside of FOX did not "pre-choose" Trump ahead of his popularity by any means. As he continued beating everyone in polling and later in actual primaries by crazy numbers, the (non-FOX) media appropriately noticed and reported on it, and he became the center of attention as is actually appropriate. There is absolutely nothing new about that in conservative politics (except for the novel opportunity to run against a female candidate who had been built up as a focal point of anger for 25 years).
The bigger problem with this notion that Trump was "fringe outside the mainstream" is this attempt to distance US conservatism from the deeply nativist, anti-immigrant stance of the Trump presidency. But that is exactly a core value of the conservative base, which I have personally observed for my whole life amongst the many conservatives in my large extended family as well as in the communities I live in. He is exactly what "regular" conservatives want. Trying to pin it on a "the media made us do it!" is a dangerous lie in that regard.
