Many people have totally lost faith in establishment politicians... our system is constantly exploited by business and even "good" politicians have shady support (through lobbying/superpacs/etc). If a mainstream politician is implicated in this mess, it gives the public concrete evidence to improve the status quo.

It's like the Snowden leaks. Many knew about the NSA conspiracies years before his information came out. For all those years the public was blind to their rights slowly slipping away as precedents were set, while those that knew were ignored as paranoid nutters. Now we can see the light.

edit: to be clear, I'm not talking about any specific politician here.
