Give both tRump and Biden the test and let the winner be president in '24. Think of all the money saved by not running another boondoggle of an election and you got Dems for another term for damn sure!
Biden would beat the crap out of tRump with half his brain tied behind his back. If tRump ever took an IQ test and got better than dead average I'd be flabbergasted. He's got the Midas Muffler touch. Everything he touches turns into iron pyrites aka Fool's Gold.
Give every candidate for any office the damn test. We'd get rid of half the republican party and a couple of useless democrats too in one fell swoop.
Too many functional idiots in there now making government non-functional when we really need to get things working as they should.
