RE: He wasn’t a Democrat.
Neither was Abe Lincoln... but he has his memorial.
Teddy Roosevelt was Republican, he is in Mount Rushmore.
That is true... But those were built when the GOP dominated government. Now the Dems dominate.
Teddy was put on Mt Rushmore to remind people of who was president when the statues were put there—Franklin Delano Roosevelt.
And Teddy was a Progressive, back before people realized that that pernicious doctrine used lies to justify theft, and then trends toward torture and murder.
