It is not at all clear to me on what basis you would characterize Teddy as a Progressive. He was a self-assured bore, opportunist and empire builder happy to follow in McKinley's footsteps. The populist of the time was still Bryant. "Progressive" in anything resembling today's meaning of the word, I don't think so.
I'm sure dude meant the other Roosevelt...but he's an idiot so what'd you expect? All teddy did was a couple of land grabs for national parks
