Based on what I know:
Citing the futility of working with Republican House leaders in a special session, Gov. Sonny Perdue on Tuesday withdrew his veto of a $700 million mid-year budget bill, but said he would give a line-item veto to the $142 million property tax rebate it contained. That money, he said, would go into reserves instead. (No special session, but a line-item veto for the property tax rebate | Political Insider)
Cagle wins because he got what he originally wanted: Money in the reserve fund
Richardson wins because he gets to claim he was for Tax refunds
Perdue Loses because he is still the first GOP Governor to veto a tax cut/refund
Update: Well, Casey was a winner till he said: “The Governor exercised strong character and courageous leadership today, and I am proud to be on his team.” Now I wonder who slipped the mescaline into his morning coffee.
