He wasn’t a Democrat.
RE: He wasnt a Democrat.
Neither was Abe Lincoln... but he has his memorial.
Teddy Roosevelt was Republican, he is in Mount Rushmore.
He was our first liberal (today’s usage) President. He favored a larger, more powerful government.
He has several million ancestors and a number of them have been American Presidents.
We know who he is if nobody else does, and it doesn't matter!
