Arizona Senator John McCain was an outlier. Fellow Republicans often criticized his independent thoughts. Staunch Conservatives viewed him as President Barack Obama's "lap dog" on foreign policy. McCain was one of few swing votes in the Senate with a Conservative majority got its way most of the time. He was his own man yet he kept the needs of others at heart and that quality led him to establishing a relationship with Pres. Barack Obama. Obama's office released the following statement upon McCain's passing:

Few of us have been tested the way John once was, or required to show the kind of courage that he did. But all of us can aspire to the courage to put the greater good above our own. At John’s best, he showed us what that means. And for that, we are all in his debt. Michelle and I send our most heartfelt condolences to Cindy and their family.
