More signs of trouble for Gov. Nathan Deal's initiative to rescue failing schools: A pro-Amendment 1 group responsible for spending tens of thousands of dollars on Georgia TV stations since September has cancelled all air time outside metro Atlanta, and curtailed its spending within the metro Atlanta market.

The group, which has made its purchases under the name of “Opportunity for All Georgia Students,” had cancelled – as of Tuesday – TV ads scheduled for airing by the top TV stations in Columbus, Augusta, Savannah, Albany, and Macon.

From an earlier Wednesday post: Shortly after Gov. Nathan Deal announced that an industry trade magazine tabbed Georgia as the No. 1 state in the nation to do business for the fourth consecutive year, the Republican drew a dotted line between the passage of his failing schools initiative and future economic development accolades.

Teachers groups and other opponents have pumped more than $5 million to oppose the plan, polls show strong resistance from both Democrats and Republicans and more than 40 school boards have come out against it.
