You cannot win US presidency twice while being dumb.
Exhibit A: George W. Bush
This says more about how much you value intelligence than whether it takes intelligence to get elected in the US.
You obviously can. An EU delegation had to explain the EU to Trump using colored cards as if he was a small child and it took many attempts before he got it. So the deciding quality must be something else.
There's nothing more amusing than watching a butt-hurt thin-skinned Trump cult member lose his shit and pathetically attempt to defend him whenever somebody makes a joke at his expense that's funny because it's true.
Trump's reaction to Robby Roadsteamer singing "Trump went on the Jeffrey Epstein plane" was priceless. If he wasn't on the plane, then why doesn't he release all the Trump-Epstein Files (TM) like he promised?

Enjoy the midterm elections, and keep up the performance for our amusement. Now do "Trump's not racist"! Then "Trump's not demented!" Then "Trump's not a rapist!" Then "Trump's not a pedophile!"
Of course you can. Your handlers have to know what they’re doing, of course, but the candidate themselves? They don’t even have to be able to speak coherently (Bush II had some issues in that direction, and of course Trump pretty much just babbles nonsense, for hours, and people put up with it).
