Why what happens in Texas matters:
Texas is the nation’s second-largest textbook market and one of the few biggies where the state picks what books schools can buy rather than leaving it up to the whims of local districts, which means publishers that get their books approved can count on millions of dollars in sales. …
Until recently, Texas’s influence was balanced to some degree by the more-liberal pull of California, the nation’s largest textbook market. But its economy is in such shambles that California has put off buying new books until at least 2014. This means that [Don] McLeroy and his ultraconservative crew have unparalleled power to shape the textbooks that children around the country read for years to come.
