I think honestly he would be Trump's preferred "successor" if Barron wasn't another 17 years from being able to run for Prez. His other kids seem mostly politically inept, especially Don Jr. This is mostly "vibes" but none of them really match to Trump's undeniable charisma. Trump is a very skilled bullsh*tter, while Don Jr., Eric, etc... aren't.
Despite literally just being 18 something strikes me as different about him.
Of course this site thinks Trump's favourite spawn is the one people speculated was autistic a few years ago, instead of the one he actually named as an advisor and quite literally groomed to succeed him... and likes porn stars that remind him of her, apparently.
If I had to bet on who the base would pick, though, it would be Eric. The guy is a true-believing kool-aid drinker. Don Jr may go hunting with Congressmen, and Ivanka may be on Lindsey Graham's speed dial, but Eric is the one in the trenches with "Re-Awaken America" religious nuts, not to mention whose wife is RNC chair. Perhaps Barron will end up hanging out with Nick Fuentes and Jackson Hinckle, or perhaps he's another Tiffany, or somewhere in between. But people are reading way too much into the son of a billionaire con-man and a model being tall, ambitious, and into networking.
