I mean, on one hand, sure, there's always corruption; nobody is perfect. But there are huge differences. "Less corrupt" is a goal worth working towards; I just don't think you can compare our current president to any other president since Nixon, and I think that this attitude that everyone is corrupt so it doesn't matter is a big part of how we got our current president.

(well... maybe Reagan. Iran-contra was shocking, and I'm a little surprised that nobody seems to think it was as big a deal as Watergate. Nixon cracked a safe. Regan... well, I'm not saying that this is what he did... but it sure looked like his deals with Iran delayed the release of US hostages until after the election. (you could also argue that those releases wouldn't have happened at all without those deals... I'm just saying, it looked pretty bad.)
