The former Secret Service agent won positive reviews during his attempt to unseat Sen. Ben Cardin. A native of New York, he earned bachelors and masters degrees from City University of New York while working as a New York police officer. While in the Secret Service, he got his MBA from Penn State. Advantages: Mr. Bongino’s Senate run gave him a state-wide volunteer network and name recognition. He is a conservative but holds more moderate views on social issues, which could work to his benefit if he makes it to the general election. Disadvantages: Mr. Bongino has never won an election, and his experience in government does not translate obviously to the job of the state’s chief executive. He is considered an upstart by some Maryland Republicans.
