Alabama Gov. Bob Riley picked up a couple of important endorsements for his plan to triple state spending on pre-kindergarten. Riley, a Republican, is meeting resistance from his own party in the state and Republicans are dragging their heels in South Carolina and Tennessee as well. The Head Start association and the organization of private providers in Alabama are both on board with Riley now. Why is this signficant? The reason is that Head Start is often wary of pre-k proposals, because they tend to be better funded. And the private providers usually balk because they fear losing their paying clients to a free service. For example, Gov. Phil Bredeson in Tennessee told the Hechinger Institute last spring that one of the biggest hurdles he faced in expanding pre-k there was the private providers group.

The tension between these groups can be found in just about all the states that are expanding their pre-k spending so it's worthwhile for journalists to pay attention to the compromises that result. In some states, such as Massachusetts, these groups have found common ground. That's interesting too.
