Where do they rank on the Good Governance-ometer?

A Bradley Smith  writes in the WSJ, regarding the recent Supreme Court ruling:  

“Already, 28 states representing 60% of the nation’s population allow corporate independent expenditures in state races. These states, including Virginia, Utah and Oregon, are hardly mismanaged. Rather, they are disproportionately among the fastest growing, best governed states in the country.

(Italics mine.)

By what statistic does he find they are “among the best governed”?

What's your stake in this, cowboy?
