Neither Trump of Bernie are " clean ". And there hasn't been a clean president for a very long time, if ever.
Bernie tried the whole " average man" crap to try to win the election. 
He just bought his third house, which was 600,000 dollars and he is a millionaire.
Trump is not any better but atleast he tells you who he really is.
The problem with Burlington college and Mrs Sanders is she was way under qualified for the position and ran the college in the ground and then took 200,000 dollars from the failing college.
This is after she bought a 10 million dollar piece of property which broke the college.
Look politics and almost all politicians are dirty people, money corrupts people. Even the Dali Lama is a multi millionaire. 
The public is so un  educated on most governmental doings. And many people just regurgitate what they hear on their particular news source or television show.
Show me a politician I'll show you a liar. We need to focus on the budget and stop selling our country.
