Joe Biden, 1974:
"Well, I'm not sure you should assume I'm not corrupt, but I thank you for that. The system does produce corruption and I think implicit in the system is corruption, when in fact whether or not you can run for public office, it'll cost a great deal money to run for the United States Senate even from a small state like Delaware, you have to go to those people who have money and they always want something."
¯\_(ツ)_/¯
