FDR wasn't a communist....like Clinton he was an opportunist. He had a number of far left/Marxist friendly people in his admin, but the chief thing he wanted was to be president and wield power. If he thought ultra-conservative economic measures would keep him in office, he would have tried to enact them.
I'm no fan of FDR, but calling all Dems commies is simply not being honest.
FDR had enough commies on his staff to make your assertion in the negative of doubtful validity.
So what if he was not a card-carrying member of the Party? He sympathized with the goals of the Communist Party - one-party rule, forever and boots stamping on the faces of the common man forever, to make no difference. You don't have to see the stripe on the skunk's back to know it stinks.
As far as calling "all" the Rodents communists, they're not that honest. Nor are they particularly intelligent. Most of them are too stupid to realize they're communists, and many don't have the guts to be honest about their affiliations with Marxism.
Look at all the Rodents who actively deny the self-evident marxism of their Kenyan Kollaborator. They're either lying about it, or just too stupid to see what all the Americans can see easily.
What about all the communists in the United States who claim that the socialism in Venezuela or Cuba or China or the old USSR or the New USSR or Cambodia, isn't "real" socialism, and that the United States is trying to implement "democratic" socialism...as they steal Congressional and Presidential elections with blatant openness? Are they stupid or criminals, or merely criminally stupid?
I'm not going to draw false distinctions and pretend that the communists in the Rodent parties are less guilty of treason merely because they're STUPID. They're still traitors and they're still harming my children's futures.
I'm fresh out of mercy for deadly enemies. I will try to relocate a black widow spider found in my back yard. By flipping her over the fence into my Rodent neighbor's property.
