4. George W. Bush
Net in line on our list of most corrupt US Presidents in history is Bush that will live on in infamy as the President who became President after one of the tightest elections in US history. He was only successful because his brother purged nearly 60,000 people from the voter poll, who were incredibly likely to vote for Al Gore. Bush also redacted evidence which showed Saudi Arabia’s link to the 9/11 attacks while there are widespread allegations that he attacked Iraq, not to go against Saddam Hussein but instead, for oil.
