The story is this. Senator John McCain had a checkup. He looked fine. But he told the doctor that his vision was acting funny and his thoughts were often foggy. The doctor decided to perform a CT scan. It was determined he had a blood clot on his left eye. It was removed, tested, and confirmed to be associated with the kind of brain cancer that killed Ted Kennedy in 2009.

Some people are saying this is not the time for politics. Cancer is not political. True, as cells, as a biological process, it's not. It will appear in a Kennedy or a McCain. But the system that treats this disease is. So, yes, this is a very good time to discuss the politics of healthcare.
