Meteor Blades gives us some numbers on the national debt by President:

Before Carter: $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.

So,
Carter added about $84.25 billion per year.
Reagan added about $200 billion per year.
Bush I added about $400 billion per year.
Clinton added about $187.5 billion per year.
Bush II added about $580.64 billion per year.

Again, this casts doubt on the notion that the GOP is the party of fiscal responsibility.
