I followed Josh Shapiro's campaigns for a number of years. Here are a few things I learned about him:
He's ambitious. It is pretty much a job requirement in politics. In his case, since he wanted to move up to higher office he kept his nose clean. There is an old saying "if a man thinks he has a chance of becoming head of a company he won't steal as much as a postage stamp." I may have the details wrong, but you get the gist.
He really does work in a bipartisan fashion. I have seen him compliment and praise Republican office holders at public meetings, and work across the aisle. in a number of ways.
He really does do what he thinks is right. I remember him as AG saying if people didn't think they had a lawyer, he was their lawyer. He meant it.
These are not bad qualities to have.
