Fiscal Conservative?

From Daily Kos:

National debt when Jimmy Carter arrived at the White House:

$660 billion.

Added during Carter's four years: $337 billion.

Added during Ronald Reagan's eight years: $1.6 trillion.

Added during George H. W. Bush's four years: $1.6 trillion.

Added during Bill Clinton's eight years: $1.5 trillion.

Added during George W. Bush's seven years, nine months: $4.5 trillion.

Portion of the $9.5 trillion added to the national debt during the past 31 years and seven months that came during Republican presidencies: $7.7 trillion.

Percentage of that $7.7 trillion added during George W. Bush's two terms: 58%.

Could somebody explain again what "fiscal conservative" means?
