I think Trump likes golf mostly for the carts. Imagine how long it would take him to waddle from hole to hole. I think Jeb would appreciate the irony. But consider all of the wearable "stored energy" that Trump carries around: "Melania, do these pants make my ass look fat?"
I don't think so. The pictures you think were altered were truncated at or above the knees. The pictures you posted were not. I think that alone accounts for any apparent "difference." You don't need to photoshop a fat guy to make him look fat; he's already done the work himself.
