He doesn't talk much about anything, just word-vomits a lot on camera and on twitter.
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.)
The swamp is overflowing and the drain is not only clogged, but non-functional. If you really believe Trump is part of the solution and not another cog in the problem machine, I'd appreciate if you elaborate why.
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.
I have heard an interesting point (relating to the FBI al least).
Disclaimer, I do not necessarily agree: since trump has been under investigation for almost his whole presidency he cannot fire people because it would now be obstruction of justice.
