Buttigieg 2020

8 years as an executive overseeing a larger group of employees and staff and a larger budget than any Senator or Representative does. South Bend has a strong mayor system so the buck really did stop with him. He also had massive interfacing with the Federal and State governments as well, plus dealt with multivariate social, economic and public relations issues. Pete can scale it up just fine, and the POTUS also has a truly insane amount of support staff, so it is the big picture that matters, and he is aces in the big picture department.
