Then Rush Limbaugh and other long time talk show Conservatives and millions of other Conservatives are also Progressives.
Heck, just about every Republican and conservative born today could call himself a Bull Mooser, and that would make him a "progressive".
I think about the only people in the GOP fold who could avoid that tag would be the paleocons who go around talking about Schumpeter and the Austrian School, and telling us we have to have a severe enough depression and panic to "do some good" by putting half the workforce on the street and destroying tens of thousands of firms so the survivors can make more money. That's the Old Guard talking, the "economic royalists" or "social Darwinists" if you will. Those guys aren't the Progressives, Bull Moosers, and Mugwumps of the modern GOP, they're the Stalwarts, the "malefactors of great wealth" of that earlier age, whose reply to depression and recession was "let 'em eat cake!"
They'd rather die fighting on their factory steps and shouting "Death to syndicalists!" than negotiate a raise. Now that is hardcore!
