 I'm going to work hard every day to transform this city. That's what it takes to build a better, stronger, safer Chicago. And everybody step up. Richard Nixon left the White House 50 years ago. Since he left office, there have been four Democrat presidents across six presidential terms. And the city of Chicago has been governed by Democrats for 93 years. But the president's state of Chicago is not, according to the current mayor, the fault of any of them.
