He's not funny.
And this idea that Trump's campaign will have turned out to be a joke the whole time is the height of liberal fantasy. They can't accept that people actually agree with Trump or like him.
You're not wrong that that is the height of liberal fantasy. Trump is serious in what he says - as are his supporters. All these rumors about him being a Democratic plant are laughable. He's just a raging bigoted blowhard with a failed business record and whose sole popularity resulted from saying "you're fired!" on a forgettable reality TV show. Trump is simply the spokesperson for the lowest common denominator, comprised primarily of privileged, angry, tinfoil hat wearing White men delusionally grasping to retake power from *those* people.
Trump is Alex Jones with a business suit and a combover.
