He has great Trump genes. The best Trump genes. Nobody's genes better than his Trump genes.
There's always Ivanka. And yet only if she
weren't his daughter would he date her. Reassuringly or otherwise.
ETA: A "really good person" can and will be interpreted as a person with goodness (on the saint/sinner spectrum), in that context.
You have to look to the world of art (painting, sculpture, characterisation in a novel or script) to find that something intended to be a person has a high
quality of personhood, i.e. is a good (representation of a) person. Doesn't make much sense at all in the context of an acknowledged actual-person qualifying even more so as such.
Given this, it starts to male sense only once you start to work on a basis (for example) that he's a shape-shifting lizard, pretending to be a person (human) and actually making a high-quality bash of it. (Not that shape-shifting lizards aren't people too, technically, but some prejudices are hard to unlearn! It's just symptomatic of my generation and I'm afraid you'll have to tolerate my little peccadillos...)
You have to bend "quality" a lot to make it the best choice of words. It's even beyond a "regular coke" being a normal-sized one (either the medium/median one, or the smallest in the trinity of sizes otherwise identified as "large" and "extra large", which is a separate complaint), rather than one which is somehow rendered periodical (or, perhaps through the inclusions of laxatives or diuretics, makes
oneself more frequently periodical in a biological manner), which is an exercise best left to the reader.
