It is funny how sometimes politicians sort of relax after leaving office. The public opinion on them can change drastically when they are just portrayed as public figures rather than the President of the United States. That type of effect has come over the former president, George W. Bush's image in the last couple of years.
These days you are going to be able to find him at football games and doing other activities that pretty much the average American likes to do. He has become a lot more relatable to people.
