Right, it's Trump's fault that the media and political opposition acted like children in opposing every word that came out of his mouth.
Apply that logic to your favorite left-leaning politician:
"The fact that Obama was always a natural born citizen would have been accepted by some Conservatives who thought he was born in Kenya, but the fact that Obama denied the claims that he was foreign-born made things worse."
When you're wrong, you're wrong. Try to own up to it without blaming the people who were actually right.
