This is such a weird sidebar. From the top, mocking Trump for losing weight is goofy. The man needed to lose some weight, he managed to do so, and he's definitely healthier now for it. He doesn't look bad in that picture because he's "gaunt" (he's not); he looks bad because he's an awful dresser, has a shitty hairdo and nauseating fake tan, and is in general a very physically unattractive man. Basically, the same reasons he's looked bad all his life.
Responding to criticism of Trump's looks by comparing Jill and Melania's looks is of course entirely irrelevant, but while we're on the subject, I'm not impressed by Trump having bought himself a trophy wife, nor by his long history of paying for sex. "Having money" is not a personal quality, and "spending money" is not a talent or skill. It's a point I've made before, but it's remarkable how much Trump's fanbase praise him for superficial "manly" attributes that he clearly doesn't possess at all. He's vain, foppish, and obsessed with his appearance. He's obese and physically weak. He's quick to take offense and complain. He never takes responsibility and regularly blames others for his mistakes. He's never served in the military, faced personal danger, or even so much as worked a day of manual labor in his life. And of course, no woman will touch him unless they've been paid or provided for. Nothing about Trump is tough, macho, or badass. He is the least manly president this nation has ever had.
