Krugman wasn't arguing facts.  He was beating up a strawman.  Fiorana says "tax rates" and Krugman trots out "actual tax collections."  Those aren't the same thing.

If you're an established business who pays the racket for "protection," you don't have "actual tax collections" that reflect the rate.  If you're not or you don't pay the greasy guys who carry violin cases the Dons in Congress  members of Congress their bribes campaign donations, you can expect to have much higher "actual tax collections."

You could say they're both wrong or they're both right, but Krugman's rebuttal consists of pretending Fiorana said something else.
