The Roanoke Times in Virginia published a piece this week by education analysts Robert Holland and Don Soifer that links to a paper they published analyzing federal pre-kindergarten programs, available at the website of the Lexington Institute , a conservative think tank.

Their argument comes at a time when Virginia Governor Tim Kaine is having trouble finding support for his plan to offer tax-funded preschool to all of the state's 4-year-olds, calling it "a large tab for scant investments.''

While most advocates for pre-kindergarten vehemently disagree with this view, reporters covering the pre-kindergarten story need to be familiar with arguments both for and against public investment in such programs as they pursue stories and keep on eye on both local and national legislation.

The Virginia story has been worth watching because Kaine has been unable to fulfill an ambitious campaign promise for universal pre-kindergarten access. He's instead shifted to trying to double the number of underprivileged 4-year-olds who might be eligible. Kaine is among the governors who have started out with big expansion dreams for pre-kindergarten, only to face economic and budget realities in their states.
