IMO, it didn't take long to figure out what Trump was peddling when he ran for office. He is one of the most, if not the most, vile, despicable, dishonest, divisive beings to ever run for office in the US. The same thing these conspiracists are doing right now is what lying Trump did during the entire campaign. These conspiracists and lying Trump have a lot in common. Trump knowing and outright lied and peddled his lies to people who either believed him, didn't bother to check into the BS, or just didn't care that he is a pathological liar and is completely devoid of morals and integrity.
Trump attacks anyone who exposes him for the pathological liar he is, so I'm not surprised that he's attacking the union president for Carrier. Another one of his "art of the deals" where, to some, he comes out smelling like a rose, WHEN IN REALITY, what he did was shovel excrement in the taxpayers' faces.
The problems is the Republicans have been dealing in lies for over 40 years. Reagan got into office talking about black welfare queens riding around in Cadillac.
The Clintons have been the major target of vast Right wing conspiracies. With the millions that Ken Starr wasted on a failed real estate deal, he only discovered that Clinton lied about having an ex-marital affair with a young woman who was old enough to consent to having sexual relations. In addition, Republicans have conducted numerous hearings on Benghazi. The Congressman who was suppose to succeed Boehner as house leader admitted on Fox News that the Benghazi hearings were done to discredit Clinton. That is why he had to step aside which made room for Paul Ryan.
Republicans, excluding McCain, were slow to denounce birthism.
Please note that I believe that Trump is despicable pond scum; however, the Republican gave him a petri dish that allowed him to grown. Without the racist, fact-free environment that Republicans fostered, Trump will be nothing but a laughing stock.
