The Cato Institute has released it's Fiscal Policy Report Card on America's Governors. You can view the individual scores here.

Sonny Perdue hasn't improved much. He's up to a "C" from last year's rating of "D", but he is still unable to match Roy Barnes's grade of "B".

Here are some of the scores for Governors considered to be potential Presidential nominees:

Bill Richardson (D-NM): "C"
Mitt Romney (R-MA): "C"
Jeb Bush (R-FL): "C"
George Pataki (R-NY): "D"
Mike Huckabee (R-AK): "F"

And just for you, Jason, your man Mark Sanford had the third best score and an overall "B".

[UPDATE] Just to be fair, I have included Cato's full remarks on Sonny Perdue:

In 2003 Sonny Perdue was inaugurated as the first Republican governor of Georgia since Reconstruction after beating tax-cutting Democratic incumbent Roy Barnes (who scored a B on the 2002 report card). Perdue ran on a pledge not to raise taxes. Once in office, however, he proposed one of the largest tax increases in Georgia history—one even bigger than the divided legislature had a stomach for. In the end, the legislature raised cigarette taxes by 25 cents and killed the rest of Perdue’s tax package. In fact, the legislature even made the Barnes property tax cut program permanent. All of this earned Perdue a midterm grade of D.

Since then, Perdue has changed course. With the help of a Republican legislature in place since 2004, he has been able to hold government spending to roughly the rate of population and inflation. He managed to cut the Medicaid rolls, too. Since 2004, he has not proposed any new taxes, and in 2005 he even proposed temporarily suspending the fuel tax to provide some relief from high gas prices. If Perdue wins a second term, he could improve his grade by finally cutting taxes for a change.
