They are very different though. One can be charismatic and charming, the other is bland and awkward.

Being famous and rich is not what got Trump in and the factors that got him in would be somewhat different for a liberal. And in the general factors that matter for a president, Zuck has about 0 of the ones that matter (charisma, likeability, relatability, toughness, outspokenness, bluster, comedy, incisiveness, a relatable or admirable background, etc).

He’s a privileged rich white kid on the spectrum, I give less-than-Bloomberg chances (same charisma, less experience and relatability).
