There are plenty of situations where he has outright lied About things he’s said on camera, so I am not sure this the proof you think it is.
Look, hes already been in office. During his first tenure he did not raid schools and deport every Hispanic he found, he did not crash the economy, he did not destroy the Constitution and make himself a dictator, he did however have the economy humming along pretty well until Covid.
Basically, he was a loudmouth blowhard on social media, and his image sucked because of it. He ended up be a decent President, nothing special. He was nothing close to the monster the media made him out to be, and certainly not worth all the celebrity tears he has caused the last 2 days.
And thats different from all other politicians how?
To use an analogy, kind of like how everyone does 5 or 10mph over the speed limit at some point but very few do 70mph down a city street in front of a school during dismissal. Both are traffic violations, but yes, they're different.
It's said that if you repeat a lie often enough people will believe it. Seems like that's been one of Trump's most used tools in his toolbox during his entire career, and there are numerous examples, some that he himself has shared.
Here's a quote from Stephanie Grisham, a former Trump press secretary:
“But no, he knows he’s lying. He used to tell me when I was press secretary, ‘Go out there and say this.’ And if it was false, he would say, ‘It doesn’t matter, Stephanie. Just say it over and over and over again, people will believe it.’ He knows his base believes in him. He knows he can basically say anything and his base will believe what he’s saying,”
Alyssa Farah Griffin, his director of strategic communications, said pretty much the same thing.
Lesley Stahl, reporting on when she confronted him before an interview about his attacks on the press:
“He said you know why I do it? I do it to discredit you all and demean you all, so when you write negative stories about me no one will believe you.”
His lying is almost pathological and he appears incapable of admitting the truth even in the face of hard evidence. Go back and look at Trump's statements about Obama's birth certificate; a series of false statements repeated over and over even after they were debunked (which essentially kicked off his political career.) Remember when Trump mistakenly said that Alabama was in the projected path of hurricane Dorian? Wouldn't have been that big a deal if he admitted the mistake, but instead he took a sharpie and hilariously "augmented" the NWS map. Caught on tape calling Apple CEO Tim Cook Tim Apple; again, not a big deal, but he denied it ever happened in spite of the evidence. And let's not even get into his repeated statements about the 2020 election results. Or his mantra that China is paying any imposed tariffs, not that they're passed onto the consumer.
Closely related, google sportswriter Rick Reilly's book about Trump and golf and take a look at some of those reports. We're not talking just kicking the ball back into the fairway, there are reports of him hitting his ball into the water but having his caddy go ahead and swap out his ball for one on the green. Again, behavior that indicates a pathology.
What makes Trump's lies so dangerous is that 1) he has a sizeable number of people with a cult like following who will believe anything he says. And 2), he's leveraged power to the point that others who know he's lying will still support a lie either for their own gain or because they're afraid to contradict him. Then, throw in the what I believe are otherwise intelligent and reasonable people but ones who have fallen into put into such a right wing silo that they aren't even aware when Trump is lying.
For the record, I'm somewhat of a unicorn in my surroundings in that I believe that an effective multiparty system is critical to the success of a nation, that absolute power corrupts, be it on the left or right. A good analogy would be the NHL without any kind of salary cap.
Anyways, sorry mods, delete if you want but I almost feel guilty that I haven't been pointing out some of these things to friends and colleagues over the past 8 years or so.
