It's not what America wanted. It's what the felon-in-chief wants, but he doesn't represent most Americans.
And even then, he only barely won the election. It was the slimmest margin since the 1800s.
He doesn't have the mandate he thinks he does, but he's a megalomaniac led by his nose ring by the psycopathic megalomaniacs behind Project 2025, which ~90% (more?) of Americans said that they didn't like when they saw it.
This is how the American people has chosen to represent themselves. The American people created the system, and the Americans knew their own system. The system produced this guy.
Now, why does it matter which percentage did he get? He got enough, did not he? And obviously he does have the mandate, because he is able to do things his way.
