As much as everyone hates Trump, he has been outstanding in highlighting the absurdly corrupt system. Can't drain the swamp you didn't know existed.
Drain the swamp was a campaign slogan and Trump repeated it a lot, but haven't really talked about systemic corruption. (See the rootstrikers movement for some serious effort on the topic.)
I.e the corruption has become so blatant as to be more widely acknowledged. I think there's an interesting possibility of "hitting rock bottom" and recovering, vs the probably rampant but less overt corruption in past decades.
