I don't recall Bush 43 accusing Democrats of being "Russian-leaning communists" even one single time, let alone so often you could talk about "all" the times he did it. I loathed nearly everything about Bush 43 and his administration, but can you cite an example or two (more would be better) where this actually happened?
I don't know if it's my memory that's faulty or yours, but you're the one lamenting our poor memory of recent events and I don't believe these particular recent events even happened.
