Next week on the Exchange, we begin with a renewed debate over organic food after a recent study found it may have few health benefits. Then, New Hampshire’s recently approved Voter ID law; we’ll see how it might affect voters and election officials in the months ahead. On Wednesday, we crunch the numbers of New Hampshire's Primary elections, and who won, who didn't and how the battles shape up for the General Election. And, we check in with the No Child Left Behind Law, as big changes are afoot for this decade old program. E-mail us at NHPR dot org and join us all next week for the Exchange each morning live at 9/and again at 8 p m....here on NHPR!
