So humans are humans–why would Democrats be any more corrupt than Republicans? Lefty sycophants OFTEN retort with that when pressed.
Because Republicans quickly get ratted out when they do something wrong, and then neither the party nor the voters support them. Democrats know that their crimes will be covered over by a fawning MSM and that the Democrats party will never take action against them!
So yeah, there is a BIG difference! (See: Joe Biden)
