Arizona Republican Senator John McCain has over his decades in government built a reputation based largely on a few key tenets. As a genuine Vietnam War hero, and as Chairman of the Senate Committee on Armed Services, he is one of the lead defenders and proponents of all things military. He relentlessly champions “good government” – i.e. spending government money more wisely and well. And he has engaged in a relentless pursuit of “campaign finance reform” so as to allegedly remove the undue influence of political donors on policy decisions.
