A rash and impulsive conservative?

The idea that the economic situation facing the country was so grave that presidential candidates should not campaign probably did not even occur to either Herbert Hoover or Franklin Roosevelt in 1932 at the beginning of the Great Depression. Yet John McCain, a man who calls himself a conservative, is taking the radical, non-cautious, non-prudent, unprecedented step of suspending his campaign and calling for candidate's debates to be delayed or canceled. When are true conservatives going to emerge to denounce this imposter?
