How much credit should a governor get for an economy's performance?

This is the question I was asked by John Finnerty, a Pennsylvania reporter.  My answer was that in general, governor's will get too much credit when things are good and too much blame when things are bad.  That said, I thought one specific policy where Pennsylvania's governor, Tom Corbett, deserves credit was his decision not to restrict fracking.

I also commented how government spending that is funded by tax dollars won't boost an economy.
