On the first day of the Republican National Convention, Sen. J.D. Vance became the vice presidential nominee to run alongside former President Donald Trump. At 39 years old, the Ohio senator is the first millennial on a major ticket.

In the past, Vance was not always a supporter of Trump, once calling him "America's Hitler," saying he was a never-Trumper, even calling him a "total fraud."

Vance is now one of the staunchest supporters and backers of Donald Trump, and he's made a 180-degree turn in the Senate, pushing bills that criminalize gender-affirming care, going against all affirmative action policies at colleges and universities, publicly supporting a 15-week abortion ban, and, among many other things, promoting the replacement theory.
