Like his ads, his candidacy can seem puzzling at times. He had never been on the political landscape before announcing his bid last May, his first run for public office. He spent more than two decades at McKinsey & Co. in Pittsburgh organizing and running its health-care consulting practice, and amassed personal wealth that's helped him fund his campaign. With about $3.3 million left in his campaign coffers — half as much as Wagner — he said he's traveled more than 80,000 miles across Pennsylvania, and points to polling that shows he's within striking distance of the state GOP-endorsed Wagner.
