I've been thinking about what I should do after I finish school this semester and a corrupt politician was the first thing that popped into my head. That probably says some pretty strange stuff about me. But anyway, I wouldn't be looking to get to the national level. Just city/county or maybe state politics would be enough.
(I'm only halfway kidding. If I actually got involved in politics, I'd probably run into too many ethical problems to become corrupt, but I like to keep my options open. )
