The Revolving Deaths Door

There's a big distinction between being at death's door as a presidential candidate and being dead. Two months ago, the John McCain campaign was waiting at death's door. Yesterday, it was Hillary Clinton. Today, Robert Novak says that the Mitt Romney presidential express is stopping at the door of doom. After South Carolina, it will be Fred Thompson. Death's door is revolving and revolving quickly. I imagine Barack Obama and Mike Huckabee will be making temporary visits sooner or later.
