Some lubricating corruption has been a staple of politics since people started living in villages to make the systems work. Nobody minds a little corruption when the politicians and policies involved benefit the populace. When Senator Jones pulls a little dirty fast one to put some kind of project in town that employs a lot of townspeople and local firms, nobody really minds if he skims a little off the top as a bonus. After all all, the Mayor is getting clout, Charlie's Construction boys get a good gig for building it, Dave and Bill and Jimmy get to work there when its done, Paul's Diner and Tom's Pub all get more business, and so on - everybody is happy so Senator Jones can have a taste as a reward. Take a look at Huey P. Long's entire career, corrupt as could be but because he built bridges, and roads, and improved people's lives he was practically a political messiah.
