The youngest child of President-elect Donald Trump cast his first ballot in a presidential general election on Tuesday, as footage from mom Melania Trump showed. 

“Voted for the first time – for his dad!” Melania tweeted about Barron, currently a freshman at NYU living in his parents' Trump Tower penthouse.

The picture depicted 6-foot, 8-inch Barron in a suit and dress shoes towering over the voting partition as he filled out his ballot in Florida where his family has their permanent residence.

The mother and son joined their husband and dad at his watch party where they were able to witness his victory over Vice President Kamala Harris.

Failed administration

Barron reportedly advised his father on ways he could increase his share of the youth vote, which he did by over 5%.

Trump also increased his percentage of the Black vote and got nearly 40% of the Hispanic vote after a campaign that highlighted Harris's place in the President Joe Biden administration, which was largely seen as a failure.

Most voters did not think they were better off under Biden than they had been under Trump during his first term from 2016 to 2020.

Harris tried to distance herself from Biden's policies, but her assurances contradicted what voters knew, which is that she was a part of and in agreement with those policies.

"Blockchain wizard"

Barron Trump was largely sheltered from public life while he was growing up in the White House and afterward. Now that he is 18 and in college, he seems to be slowly becoming more of a public figure.

He recently got involved in his father's venture into cryptocurrency, and hailed by his father as being knowledgable about it.

“Barron’s a young guy, but he knows – he talks about his [crypto] wallet, he’s got four wallets or something, and I’ll say ‘what is a wallet?’ But he knows it inside out," Trump said proudly at the time of the launch.

Bitcoin jumped quickly up over $75,000 when Donald Trump was declared the winner of the presidential race early on Wednesday, the highest it has ever been.

Al three stock market indexes also hit record highs.

It's as if the financial markets know who would be more advantageous as president.
