Trump stumbled into winning because of Hillary’s shittiness not because of Putin pulling the strings and spreading lies. If you believe that you’re just as dumb as the people that fell for all the fake news put out by Russia.
Trump did more than stumble into it. He played the game correctly in every way Clinton did not. He let the outrage machine run full tilt 24/7 on a bunch of nothing, giving him free publicity since they couldn't shut the fuck up and ran shit like"Is it racist for Trump to order General Tso's Chicken?". They'd cried wolf so many times no one who wasn't already voting Clinton gave a shit when they got stuff like the Pussy Grabbing Tape that might have been able to hurt his numbers. He also knew exactly how to play the EC game too; he didn't even bother with California and put minimal time in solid-red states, focusing on swing states he felt he could turn. And it worked.
The fact Clinton ran such an incredibly awful and tone-deaf campaign was just a bonus.
Russia "meddling in our elections" is nothing new.
Ted Kennedy straight up begged the Soviets for help against Regan in the 80s. The US does the exact same shit in Russia, and other countries as well. And its not just Russia who does it. China, Saudi Arabia, etc.
Russia put their infowarriors behind Trump for two reasons. First, he was a disruptive outsider, and an off-balance US is in Russia's best interest. Second, Clinton was likely to continue & ramp-up US involvement in Syria, while taking a hard line on Asad's ouster; Trump was more likely to scale down or stop involvement, and probably would easier to convince to allow Asad to remain Syria's head of state.
John Walker Flynt-Wu wouldn't know anything about running a campaign, since his idea of gathering votes is "Vote for me or you're a bad ally!"
